BASE METALS East (Alaska), Agua Rica and El Pachón (Argentina), Las Bambas, Quellaveco, Toromocho and La Granja, (Peru), Cobre Panamá (Panama), El Arco (Mexico) and Udokan (Russia) are just some of these. Zinc and Lead: New Capacity Needed Three companies dominate world zinc pro- duction: Vedanta Resources, Xstrata and Teck, with other significant players in the market including Minmetals Resources, Glencore, Volcan Cia Minera, Boliden and Sumitomo. In terms of zinc smelting, Nyrstar is the individual leader by a con- siderable margin, followed in capacity terms by Korea Zinc, Xstrata, Boliden, Glencore, Votorantim and Vedanta. Speaking at the ILZSG annual meet- ing, Stephen Wilkinson, executive direc- COMPANY PROFILE-PAID ADVERTISEMENT Lead ingots. (Photo courtesy of Boliden) U.S. Tsubaki Power Transmission, LLC is a leading manufacturer and supplier of state-of-the-art power transmission and motion control products and is a glob- al leader in roller and conveyor chain production. U.S. Tsubaki is the largest global subsidiary of Japan's Tsubakimoto Chain Company which was founded in 1917. Today, Tsubaki's products are marketed in over 70 countries. U.S. Tsubaki's corporate headquarters and main distribution warehouse are just outside of Chicago in Wheeling, IL and it has full manufacturing facilities in Holyoke, MA and Sandusky, OH. In addition to this it has service centers strategically located in Los Angeles, CA; Dallas, TX; Atlanta, GA; Philadelphia, PA; Charlotte, NC and Anoka, MN. The TSUBAKI name is synonymous with excel- lence in quality, dependability and customer service. An intense focus on research and development, along with constant modernization of its production facilities are among the key components in Tsubaki's ability to successfully meet the ever- changing needs of the marketplace. Leveraging its vast, international network of corporate and industrial resources, U.S. Tsubaki offers customers the finest power transmission prod- ucts in the world. According to the company, it is well positioned to meet the challenges of the 21st century and beyond as it strives to be the "Best Value" suppli- er in the industry. Tsubaki's global presence affords the company with unprecedented opportunities to market advanced new products and technologies, and to utilize the intel- lectual assets of what it characterizes as "some of the brightest minds in business and engineering from around the world." This strength, combined with its continuous improvement of quality and processes, has U.S. Tsubaki poised for lasting growth now, and well into the future. U.S. Tsubaki's industrial group is currently com- prised of 4 business units: the Roller Chain Division, 94 E&MJ; • JUNE 2012 Engineering Chain Division, Power Transmission Components Division (which includes Sprockets) and the KabelSchlepp Cable & Hose Carrier Division. The Roller Chain Division provides some of the most versatile products on the market. Tsubaki innova- tions have yielded popular problem solvers such as self-lube Lambda® series chain, corrosion resistant Neptune® chain, fatigue resistant Super Chains, and rugged Energy Series™ oilfield chains. Attachment chains used for conveying a variety of products are also available in a range of configurations. U.S. Tsubaki's Engineering Chain Division starts with the high-performance base materials to ensure increased wear life. They offer heavy-duty chains designed specifically to meet the demanding needs of a vast array of industries - all designed to prolong wear life under rigorous operating conditions. U.S. Tsubaki sprockets are built from top-grade, heat-treated carbon steel to offer long wear life, resist abrasion, and withstand heavy shock loads. Alloy and stainless steel sprockets are also available for extra corrosion resistance and food-grade applications. Precision manufacturing at their ISO-certified facilities ensures that every U.S. Tsubaki sprocket stands up to critical design specifications and meets the highest quality standards. Power Transmission Components products include all Tsubakimoto products other than chain and sprock- ets. A partial listing consists of belts, cam clutches, actuators, dampers, overload protection and reducers. The Cable & Hose Carrier Division supplies steel, high-grade stainless steel, solid plastic cable carriers and hybrid cable carriers with aluminum stays and plastic sidebands, in standard sizes or tailor-made to an individual customer's exact size and application requirements. tor of the International Zinc Association, reminded delegates of the increasing role being taken by Chinese companies in world zinc production. High-profile projects involving Chinese investment include Dudar (Pakistan), Turmurtin (Mongolia), and Broken Hill, Rosebery and Century (Australia), while Chinese interests now have a 17% equity stake in the main Canadian zinc producer, Teck. Chinese control now totals around 37% of the world's mine supply, he said, with further interests in development projects such as Izok Lake, Wolverine, Dugald River and Selwyn. Recent consolidation within the zinc industry has included Vedanta's purchase of Anglo American's zinc interests, and Nyrstar's acquisition of Breakwater Resources. Meanwhile, recent additions to supply have included Al Masane (Saudi Arabia; 25,000 mt/y), Halfmile Lake (Canada; 55,000 t/y), Wolverine (Canada; 53,000 t/y) and expansions at both Colquijirca and Antamina in Peru, which have added 115,000 t to the mar- ket. This year, the commissioning of Perkoa in Burkina Faso should bring 90,000 t of new capacity. However, as Brian Hearne, COO for Xstrata Zinc in Australia, told analysts in a presentation last year, over the next few years new capacity coming on stream looks likely to fall well short of capacity lost through mine closures. Actual and potential closures during 2012-2013 include Brunswick, Perseverance and El Mochito, he said, while mines set to close by 2015 include Century, Lisheen, Duck Pond and Golden Grove. With Skorpion, Myra Falls, Canning- ton, Guemassa and Cayeli probably all being exhausted by 2017, cumulative lost production will then run to 1.9 mil- lion mt of zinc and 470,000 mt of lead, he said.
