FORBES MAGAZINE - BENEATH THE SURFACE

4th August, 2017 I By Varsha Meghani
Hindustan Zinc - India's Super 50 Companies 2017 by Forbes India.

What makes it Super
  • Access to high quality grades of ore lends it a ‘natural’ advantage
  • Tight control on costs helps it retain it healthy margins
  • Quick adoption of the best-in-class technologies
  • The integrated nature of their operations adds to their cost advantage.

A 100-tonne truck emerges from pitch darkness and rumbles past us. Outfitted with helmets, rubber boots and fluorescent overalls, we’re seated in an SUV, waiting to plunge into the same abyss. Around us hills dot the dry landscape.

We’re at the mouth off the Sindesar Khurd, an underground zinc-lead mine operated by Hindustan Zinc in Dariba on the outskirts of Udaipur in Rajasthan. About an hour ago, a blasting had been carried out in the 500-metre deep mine. The truck that crossed us had scooped up the broken rock and was on its way to a nearby mill where the zinc-lead ore would be separated from the waste.

This extraction of zinc and lead - and silver as a by-product–is a thriving business; one that has catapulted Hindustan Zinc from deep losses, when it was a government run–entity, to huge profits after Anil Agarwal’s Vedanta Ltd (formerly Sesa Sterlite) bought its first tranche of the company’s shares in 2002. Last fiscal, the company – 29.5 percent of it is still owned by the government–reported earnings before interest, tax, depreciation and amortisation (Ebitda) of Rs. 9,734 crore on revenues of Rs. 18,642 crore. Meanwhile, cash reserves stood at Rs. 16,065 crore. This, despite declaring an interim and special dividend totalling Rs. 27,157 crore–the highest ever paid by an Indian company in a single financial year claims the company, which trades at Rs. 274 on both the BSE and the NSE (as of July 14). “When our balance sheet became very fat, we decided to share the money with the government, our shareholders and us”, jokes Sunil Duggal, CEO, Hindustan Zinc.

Despite the huge outflow, the company’s expansion plans remain undented. With a current output of 1 million metric tonnes per annum (MMTPA) of refined metal, Hindustan Zinc is the second largest Zinc producer in the world – after Anglo-Swiss mining giant Glencore – and seems well on its way to achieving a targeted output of 1.2 MMTPA by FY2019. It is among the world’s least expensive zinc producers, and also Vedanta’s most profitable unit. In India, it enjoys a near-monopoly (the only other Zinc producer, Binani Zinc, produces 0.03 MMTPA), meeting 80 percent of the domestic demand for the metal that is largely used as a coating to protect steel from rusting. Clearly, Duggal, 55, has much to smile to about.

Our SUV makes its way into the mine. Floodlights blinking, we drive through the mine passages, first 300 metres underground and then 200 metres further. The air becomes heavy and the darkness is interrupted by light bulbs hanging from the rock ceiling at intervals of a few metres. Jumbos–large vehicles that blast through the ore body–navigate the rocky terrain, making way for our car.

Huge mineral wealth is buried deep within those rocks. In fact, some of the richest ore bodies are found in the five zinc–lead mines owned by Hindustan zinc spread across Rajasthan. At Sindesar Khurd, the ore grade–the concentration of mineral within an ore–is 6 percent. While at Rampura Agucha–the company’s flagship mine, and also the world’s largest zinc-producing mine – the ore grade is even higher: “The open cast pit mine at Rampura Agucha has a grade quality of 13 percent, while the underground mine has a grade of 14.1 percent. Globally the average is about 3 percent”, says Ashutosh Somani, metals and mining analyst, institutional equities research, JM Financial.

This natural bounty has ensured that Hindustan Zinc maintains its advantage on the cost of production of zinc. At around $800 per tonne, the company’s cost of production is around 30 percent lower than that of its global peers, says Andrew Thomas, principal analyst, zinc markets, at Wood Mackenzie, an Edinburgh-headquartered research consultancy.

Remarkably, Hindustan Zinc has been able to maintain this cost over the years; around 15 years ago, at the time Vedanta stepped in, the cost was the same. What was different, however, was the price of zinc on the London Metal Exchange (LME). Back then it hovered around $800 to $850 per tonne, says Duggal, which meant that the company was largely loss making. So much so that in 2002 when Vedanta bid for a controlling stake in Hindustan Zinc, it encountered little competition; it bought a 26 percent stake from the government for Rs. 445 crore, while another 20 percent was acquired from the public. (In 2003, Vedanta acquired an additional 18.9 percent stake from the government for Rs. 324 crore, taking its total ownership in Hindustan Zinc to 64.9 per cent.)

Around the mid–2000s a China driven commodities boom began, with the prices of oil to iron ore and zinc shooting up. Hindustan Zinc’s profit followed suit; in fact its margins only became fatter as its cost of production remained steady.

Today, zinc prices move between $2500 to $2700 per tonne on the LME. “We never look at commodity cycles when looking at production,” says Duggal, pointing out that even at about $1400 per tonne – the lowest zinc prices have sunk to over the last five to six years–Hindustan Zinc still pocketed a good margin, given its $800 per tonne cost of production. Even at the height of the global financial meltdown in 2009, when zinc prices plummeted to around $1100 per tonne and prompted producers worldwide to shut mines or halt production, Hindustan Zinc made money. “So that [global zinc prices] is not a topic for me. The only topic is first to control costs and second to increase volumes”, adds Duggal.

Apart from the low cost of labour in India, Hindustan Zinc’s access to abundant, and high grade, ore is just one of the factors that enables it to maintain its low cost of production. After all, these resources were available to it even when it was an unprofitable, state–run company.

In fact, at the time of Vedanta take over in 2002, Hindustan Zinc produced only 0.2 MMTPA of refined metal. “Globally, we were nowhere,” says Naveen Singhal, president and director, projects, at Hindustan Zinc. “But our chairman’s [Anil Agarwal], vision was to make the company a global first or second.”

Upping production was key to that vision. And so from 2003 to 2005, Hindustan Zinc undertook what Singhal describes as “Phase 1 of the expansion journey, targeting 0.5 MMTPA of ramped up capacity. The challenge however, was to keep capex costs low so as to make the project financially viable, given the low zinc prices at that time, says Singhal. Also, project delays had to be avoided so as not to get caught in a spiral of interest payments. “We engaged the best of contractors with the right technology and right infrastructure practices so that they could do our project right”, he says.

In addition to mine expansion, zinc and lead smelters, and the company’s first thermal capacity power plant were built. “Our smelters are power intensive. If we didn’t have a power plant, firstly our costs would be higher and secondly getting reliable power would be an issue. Without reliable power, we can lose millions of dollars in a day”, says Singhal. This integrated project was completed in record time and at a cost 40 percent lower than the global benchmark, because of the right technology partners, as well as the low cost of labour that India enjoys, he adds.

By the time the project ended, metal prices started soaring and Hindustan Zinc began raking in the profits. Hungry for more, it eyed large volumes, targeting 0.8 MMTPA of capacity expansion by 2008 as part of Phase 2. This time too, the company ramped up not just its mines, but also the capacity of its smelters and power plants. “Each time we spent money, we spent it in all three areas”, says Singhal. The fact that Hindustan Zinc’s mines and smelters and power plants are located close to each other reduces transportation costs, while the power plants meet 94 percent of company’s energy needs, says Somani. “The integrated nature of their operations adds to their cost advantage,” he says.

Currently, Hindustan Zinc produces 0.9 MMTPA of metal and is on track to meet its next target of 1.2 MMTPA by FY 2019. As part of this phase, in 2012, it found that the open pit production at Rampura Agucha, responsible for 70 to 85 percent of the total output was tapering. Exploration studies revealed that a kilometre beneath the earth’s surface the reserves were still rich. Swiftly, the management implemented a transition from open cast mining to underground mining. Here too, investments in world–class technology, including the building of 1 km–long shafts at Rampura Agucha and Sindesar Khurd mines, are underway to increase efficiencies. Digital technologies, such as wifi infrastructure within their mines, are also being built to connect their operations and resources in real time. “It is the next generation of underground mining,” says Duggal.

The challenge, however, will be to compensate for declining output from open cast mining, while still meeting the 1.2 MMTPA target. This is important for retaining volume and, therefore, cost advantage. At present, the company produces 0.4 MMTPA of metal from underground mining operations. “We are not going from 0.9 to 1.2 MMTPA, but from 0.4 to 1.2 MMTPA. It is a three-fold expansion,” says Singhal, adding that over the last 10 to 12 years the company has spent more than $3 billion on expansion work.

As we drive through the mine passages, making our way back to the top, the air becomes lighter. Metres away from the mouth of the mine sunlight floods into the SUV. The full extent of the riches that lie beneath the surface become astonishingly clear.

MY SILVER GLITTERS MORE THAN A GOLD - ASK FOR ZINC

While travelling from “Ask for Zinc - A to Zinc in our Lives”, there also falls one letter 'S', denoting Silver. A market that is dominated majorly by imports in India with Hindustan Zinc as the only primary Silver producer in India with over 95% market share in production.
Who knew, the lines that we see on the rear windscreen of cars, which are used for defrosting and defogging, are made from Silver. Surprisingly, in the United States, an alloy can only be called Silver if it has at least 90% Pure Silver.  Who knew that Silver has its origin from a Sanskrit word, later derived from Latin  ARGUNAS, meaning Shining.
Globally, the highest usage of Silver is Industrial Fabrication (51%), followed by Coins and Bars (25%), Jewellery (19%) and Silverware (5%). In India, the highest usage of Silver is Coins and Bars (37%), followed by Jewellery (30%), Silverware (17%) and Industrial Fabrication (16%).
Used in conjunction with almost every common industry, Silver makes itself practically indispensable.
Hindustan Zinc is aiming to produce 1000 tonnes of Silver from current level of about 500 tonnes annually. The company proposes to capture 10% of the Silver consumption market in India from the current level of just about 5%.

HISTORY SAYS IT ALL…
Silver is derived from the Anglo-Saxon word for Silver, 'Siolfor,' which itself comes from ancient Germanic 'Silabar'. Silver's chemical symbol (Ag) is an abbreviation of the Latin word for Silver, 'Argentum'. The Latin word originates from Argunas, a Sanskrit word meaning shining.
One of the most precious ancient metals to have roots in Zinc, Silver is believed to be discovered around 5000 BC. While Silver objects have been found dating back before 4000 BC, mankind learned to separate Silver from Lead in 3000 BC. Around 700 B.C. early Mediterranean civilizations were using the brilliant white metal as currency.
Gold was considered to be the skin of the ancient Egyptian gods, but their bones were thought to be of Silver. In ancient Egypt, Silver was considered much more valuable than Gold. It was rare in existence and on the list of valuables. Items of Silver were listed above those of Gold during the Old Kingdom.
The mining of Silver began between 5,000 and 6,000 years ago in Anatolia, or what is now Turkey. One of the first five metals to be discovered by the mankind. Over the next several centuries, the epicentre of Silver mining shifted from Greece to Spain to Germany to Eastern Europe.

PARKES PROCESS - EXTRACTION OF SILVER FROM ZINC
There have been many ways of extraction of Silver through smelting process.  One of them has been the Parkes Process, a pyro metallurgical industrial process for removing Silver from Lead during the production of bullion. It is an example of liquid-liquid extraction.
Parkes process (patented in 1850), involves adding Zinc to Lead and melting the two together. When stirred, the molten Zinc reacts and forms compounds with any Silver and Gold present in the Lead. These Zinc compounds are lighter than the Lead and, on cooling, form a crust that can be readily removed.
The process takes advantage of two liquid-state properties of Zinc - the First is that Zinc is immiscible with Lead and the Second that Silver is 3000 times more soluble in Zinc than it is in Lead.
When Zinc is added to liquid Lead that contains Silver as a contaminant, the Silver preferentially migrates into the Zinc. Since Zinc is immiscible in Lead, it remains in a separate layer and is easily removed. The Zinc-Silver solution is then heated until the Zinc vaporizes, leaving nearly pure Silver. If Gold is present in the liquid Lead, it can also be removed and isolated by the same process.

SILVER ELECTROPLATING -
A CHANGE IN ERA
Silver's industrial role is much more than that of Gold and it is for this reason that a shortage of Silver has always had higher negative implications than there would be if there was a shortage of Gold.
Silver has the highest electrical conductivity amongst all the metals, which is why it is used as an alloyed form for electrical contacts. Satellites, lasers, high-tech weaponry, robotics, telecommunications, all need Silver. Conductors, contracts, switches and fuses need Silver too because of its non-corroding or non-overheating properties.
Engine bearings rely on Silver. The strongest bearing is made from steel and is electroplated with Silver. Silver's high melting point allows it to withstand the high temperature of engines and Silver's lubricant-like features help reduce friction between a ball bearing and its housing. Due to Silver's ability to absorb oxygen, it is being researched as a possible substitute for platinum to catalyse oxidation of matter collected in diesel engine filters. The other industrial applications of Silver electroplating include use in electrical parts and components like Copper connectors and Brass connectors.

SOLAR PANELS - THE POWER OF SUN, BROUGHT TO YOU BY SILVER
If we add the amount of Solar Energy that is absorbed by the Earth's atmosphere, land and oceans every year, we end up with approximately 3,850,000 EJ (exajoules or 10^18 joules). To put it in more understandable terms, this amount of energy is equivalent to  :  2.7 million earthquakes of the same size as the Tohoku earthquake in Japan (2011) - 40,000 times the total energy consumption in the United States - 8,000 times the total consumption in the whole world -  40% of the energy that is required to heat the entire volume of water we have on Earth by 1°Celsius. Every square meter of our planet receives around 1,366 watts of direct Solar radiation.
In America, one solar panel system is installed every four minutes. NASA is currently working on a Solar-powered aircraft.
Silver is a unique metal. It has the highest electrical and thermal conductivity of all metals, and it's the most reflective. These physical properties make Silver a highly valued industrial metal, especially when used in Solar cells.
Industry estimates that 40 tonnes of Silver is required to produce panels that would generate 1 GW of Solar Power. With this industry (solar) virtually non-existent 10 years ago, Silver demand in the Solar industry is growing at a fast clip as an alternate form of Energy source in India.
Silver is a primary ingredient in photovoltaic cells, and 90% of crystalline Silicon photovoltaic cells use Silver paste. When sunlight hits the silicon cell it generates electrons. The Silver used in the cell works as a conductor to collect these electrons in order to form a useful electric current. The Silver then transports the electricity out of the cell so it can be used. Further, the conductive nature of Silver enhances the reflection of the sunlight to improve the Energy that is collected. Therefore, if it wasn't for Silver, Solar wouldn't be as efficient in turning sunlight into Energy.
India is currently 100% importer of Solar parts where Silver is used, the major countries from where it is being imported are China and Japan. Taking forward the vision of our Prime Minister to produce 50 GW of Solar Energy, and producing Solar parts, Indian consumption of Silver will be all set to increase by about 2000 tonnes. This would also create large ancillary industries and ample employment opportunities.
California is home to the largest Solar Power Plant in the world, located in the Mojave Desert. It spans 1,000 acres. California also dominates the Solar Power market, with a market share of 44% in 2015. California, Arizona, and North Carolina are the top three US states for Solar power, based on the amount of cumulative Solar electric capacity installed. There are now nine states in the U.S. where 100% of new electrical energy comes from Solar Power.
As it turns out, Solar Energy wouldn't work the same way if it wasn't for Silver.

HEALTH - SILVER GLITTERS IN MY MEDICINE
Hippocrates, "The Father of Medicine", knew of Silver's healing and anti-disease properties. In World War I, before the widespread use of antibiotics, it was imperative on the battlefield. Silver foil was wrapped around wounds to help them heal.
Silver, a germicidal, kills bacteria and other lower organisms. Silver ions act as a catalyst by absorbing oxygen, which kills bacteria by interfering with their respiration. This antibiotic property, along with its non-toxicity, has given Silver an essential role in medicine for thousands of years.
In medicine, Silver is incorporated into wound dressings to treat external infections and also used as an antibiotic coating in medical devices. It is also used in some medical applications, such as urinary catheters (where tentative evidence indicates it reduces catheter-related urinary tract infections) and in endotracheal breathing tubes (where evidence suggests it reduces ventilator-associated pneumonia). The Silver ion (Ag+) is bio-active and in sufficient concentration readily kills bacteria in vitro. Silver is also used in other medical instruments and is a key part of the technology behind X-rays. It has also been used in eye drops and in dental hygiene to cure and prevent infection. Silver Sulfadiazine is especially useful for burn victims because it kills bacteria while also allowing the skin to regrow. Silver ion treatments can heal bone infections and allow regeneration of damaged tissue.
Today, the presence of antibiotic-resistant superbugs increases the demand for Silver in hospitals. Small amounts of Silver can coat hospital surfaces and medical equipment to prevent the spread of pathogens.
Silver and Silver nanoparticles are also used as an antimicrobial in a variety of industrial, healthcare, and domestic applications.

FORECAST - THE SILVER INSTITUTE
As per Indian Minerals Yearbook, published by Indian Bureau of Mines, India is the biggest importer and largest consumer of Silver in the world. Considering the current pattern of utilisation of Silver in the country and the anticipated increase in the GDP, the future demand for Silver is likely to exceed 6,000 tonnes per annum by 2017 as per the report of the Working Group on Mineral Exploration and Development (Other than Coal & Lignite) for the XII Five Year Plan (2012-2017). There is a need for intensifying the exploration for identification of more Silver bearing resources from which Silver is recovered as a by-product.
Silver growth is only likely to increase in India in the coming years since India is growing very aggressively in the areas of Make in India, Digital India and Solar Energy. As compared to the world, India has been slow towards utilization of silver for industrial usage with mere 16%, as compared to global usage of 51%. Though we are growing in terms of utilization of Silver in jewelry and Silver-ware, the real boost will come with Digital India and development of domestic solar energy market where Silver will be used.
