Main page ENTERPRISE Limited Liability Company "Mednogorsk Copper and Sulfur Combine" is located in the Orenburg region in the city of Mednogorsk. The territory of the company is an elongated rectangle with an area of about 60 hectares, located parallel to the Blyava river. At the industrial site of the company there is a Mednogorsk CHPP, which is not part of the plant. The location of the industrial site was chosen taking into account the proximity of the raw material base. The Mednogorsk copper-sulfur plant was built in 1939 to process copper ores from the Blyavinsky deposit using the improved pyrite smelting method (Orkla process) to obtain blister copper and elemental sulfur from metallurgical gases. The design capacity of the enterprise for the processing of ore raw materials was determined at 700 thousand tons per year. In 1959-1962, a contractile smelting department was built for enrichment of poor copper mattes and a sulfuric acid shop for the utilization of metallurgical gases of contractile smelting and the production of sulfuric acid. In recent years, the enterprise has been processing copper concentrates, copper ores, clinker produced by zinc plants, while producing blister copper and sulfuric acid. The plant operates according to the following technological scheme: briquetting of raw materials - melting briquettes in shaft furnaces - converting mattes - casting blister copper into large-sized ingots. The gases from the contractile smelting and converters are used for the production of sulfuric acid by the contact method. The enterprise includes: copper smelting shop - processes copper-containing raw materials to obtain blister copper; briquetting factory - produces briquetting on roller presses of copper-containing raw materials; sulfuric acid shop - processes purified sulfur-containing gases from the copper smelting shop to produce sulfuric acid. There are other auxiliary workshops and engineering services: a railway workshop, a workshop for the production of technological oxygen, a mining workshop, a mechanical repair workshop, an auto-tractor workshop, an energy workshop, and others. LLC "Mednogorsk copper-sulfuric plant" works with the following processing enterprises and suppliers of raw materials: with OJSC Uralelektromed, Verkhnyaya Pyshma, for the processing of blister copper; with OJSC Gaysky GOK for the supply of flux ore, copper concentrate; with JSC "Chelyabinsk Zinc Plant" for the supply of clinker; with JSC "Electrozinc", Vladikavkaz for the supply of clinker; with CJSC Buribaysky GOK for the supply of copper concentrate; with LLP "Yubileiny" Kazakhstan for the supply of crushed quartzite containing precious metals.
