a look at the largest copper smelters

Four of the five largest refineriesand 10 of the top 20are located in mainland China. The five largest alonehave a combined capacity of over 7million metric tons or about 33% of global capacity.

Listed are the common names of each smelter followed by the owner in parentheses. The smelter's annual refined copper capacity is then noted in thousands of metric tons (kilotonnes) per anum (kta), or million metric tons per anum (mmta).

India's largest copper refiner, operated by Hindalco and located in Gujarat, Birla first began copper production in 1998. After numerous expansions, it now has a capacity of around 1.5million metric tons per annum.

The Pyshma electrolytic copper refinery first began production in 1934. Located inSverdlovsk Oblast, Russia, Pyshma is operated byUralelectromed, the publicly traded arm of Ural Mining and Metallurgical Company.

Established in 1958, Yunnan Copper is China's third largest producer of copper-based on total capacity. It's smelter in Qingyuan, Guangdong province, is a joint venture betweenYunnan Copper and China Nonferrous Metals Group, which mainly processes blister from the Chambishi smelter in Zambia.

The Toyo Smelter and Refinery, located in the cities of Saijo and Nihama, Japan, are operated by Sumitomo Metals Mining Co. Ltd. Fed by concentrate from South America, Australia, and southeast Asia, including that from the Sierra Gorda mine, the refinery also extracts gold and molybdenum as by-products from the copper.

The Amarillo Refinery in northern Texas employs over 300 staff, refining copper cathode and nickel sulfate. The copper refinery was commissioned in 1974 by Asarco Inc. and is now owned and operated by Grupo Mexico.

about us

PT Smelting was established in February 1996 as the first copper smelter and refinery in Indonesia with approximately US $500 million for direct construction cost.

The plant was originally designed to produce 200,000 tpy of "LME Grade A" copper cathode from 660,000 tpy of copper concentrate supplied by domestic mining companies. Currently copper cathode production level has been expanded to over 300,000 TPY, with priority of it is sold for Indonesian market and the rest is exported to Asian market. By-products of sulfuric acid, granulated slag and gypsum are delivered to local market, and anode slime and copper telluride are exported to international market.

Rnnskr in Skelleftehamn is one of the world's most efficient copper smelters. The plant receives deliveries of copper and lead concentrates from our own mines and from external suppliers. Today the smelter is a world leader in electronics recycling thanks to investments and developments in Kaldo technology. We extract primarily copper, gold and silver from these materials. Rnnskr is our biggest production unit and the biggest private employer in the region.

65 per cent of all copper produced is used to generate and conduct electricity. The supply of copper is therefore crucial for the transition to alternative energy sources like wind, solar and hydro power, where the copper is needed in the first stage to generate electricity and in the second stage to carry the energy over long distances with low losses.

Studies show that when copper is used for the purposes of energy efficiency improvements, it can deliver CO2 reductions that counteract the emissions involved in producing the copper by a factor of 250.

Boliden is investing SEK 750 m in a leaching plant at Rnnskr. The plant, aims to extract more metal from residual material. Simultaneously, the amount of waste for disposal in the deep repository at Rnnskr will be reduced.

The investment is fully in line with the strategy to extract as much metal as technically possible from existing raw materials. This significant improvement in Rnnskrs resource efficiency will both enhance the smelters competitiveness and reduce the volumes of materials for disposal.

The leaching plant comprises a new 45 x 135 meter building located next to the quay in the Rnnskr industrial area. The annual production will total 25 ktonnes of lead sulphate and 25 ktonnes of copper/zinc sulphate.

We own and operate the Columbus Metallurgical Complex, a smelting facility and base metal refinery situated between our Stillwater mine and the town of Billings, Montana. It is one of the worlds largest producers of PGMs recycled from spent automotive catalytic converters.

The Columbus Metallurgical Complex produces a 2E PGM-rich filter cake (in addition to other by-product metals) which is further refined to palladium and platinum metal by a third-party precious metal refiner.

The Columbus Metallurgical Complex consists of a smelter, that includes a concentrate drying plant, two electric furnaces, two top blown rotary convertors, a matte granulator, gas handling and solution regeneration systems. The smelters maximum design capacity is 20,000 lbs/hour (operates at 90% utilisation) which is presently limited until upgrades to the concentrate drying plant and convertor/granulation circuit are completed. These improvements are scheduled such that the capacity of the smelter aligns with the Blitz/East Boulder production increases.

At the smelter, the gases released from the smelting operations are routed through a state-of-the-art dual alkaline, gas/liquid scrubbing system. The scrubber is so efficient and effective that less than 3% of the smelters permitted emissions are discharged into the environment.

In addition to the smelter, the base metals refinery has a capacity of 1,300 lbs/hour of matte but is limited by overall copper electrowinning (EW) capacity. The copper EW circuit operates 24/7 even though the rest of plant operates approximately one half of a week, and therefore the copper circuit must be expanded to accommodate the increased quantities of copper that Blitz and East Boulder will deliver.

The base metal refinery utilises a sulphuric acid solution to dissolve out nickel, copper, cobalt and any residual iron from the PGM-bearing converter matter. The base metal refinery produces a palladium, platinum and rhodium-rich filter cake (from the recycling process), which is further processed to refined metal by a third-party refiner. Refined metals from our mine production are sold to Johnson Matthey and Tiffany & Co., while refined metals from our recycling business are normally delivered to counterparties.

Spent catalytic converters are sourced from third-party suppliers, either by outright purchase or on a toll processing fee basis. Third-party suppliers collect recycling materials primarily from automobile repair shops and automobile yards that process scrapped vehicles. PGMs are also recycled from petroleum refinery catalysts and other PGM-bearing materials.

Prior to processing, recycling materials are weighed, crushed and sampled in a state-of-the-art assay lab at Columbus utilising an automated X-ray process that provides greater accuracy and faster processing times than conventional fire assay methods. Crushed catalyst material is blended and processed with concentrates from our Stillwater and East Boulder mines.

Blending materials from two different sources gives us a competitive advantage over other recycling facilities which lack access to mined production. It also provides processing efficiencies the concentrates from our Montana mines contain quantities of nickel and copper which facilitate extraction of the PGMs from the recycled material.

Our recycling operations conserve natural resources, energy and landfill space, reducing the environmental impact associated with acquiring mined material. Recycling is not only resource-efficient and environmentally sound; it also contributes to the resilience, efficiency and predictability of our Columbus operation.
