In a multiple hearth roaster, copper concentrate of composition Cu FeS2 33% Cu2S 7%, FeS2 34%, SiO2 19% and moisture 7% is roasted. All iron is oxidized to Fe2O3, and 50% of Cu oxidizes to CuO and rest to CuS. The furnace gases analyze 12% O2 and leaving the furnace at 900K. The roast product is also discharge at 900K. Reactans enter at 298K.

Although copper occurs naturally in a pure state, it's primarily mined from chalcopyrite, bornite, and malachite. Copper ore is extracted from the earth, then converted into copper concentrate, which is then roasted, smelted and converted into refined copper.
from the concentrate into the molten matte as possible. The matte grades (the Cu percentage) can vary depending on the Cu content in the original ore and on the type and operating conditions of the smelting furnace. Poor extraction of copper from the concentrate leads to significant copper …

This technology is applicable to the recovery of nickel, cobalt, copper, and platinum group metals from furnace or converter slags emanating from copper or nickel smelters treating sulphide concentrates. Pilot-plant testwork at Mintek has demonstrated recoveries of 98% for nickel and over 80% for cobalt, at power levels of up to 600 kW.

Apr 13, 2016· The Problem with Copper for Porphyry ores and Chalcocite and Chalcopyrite Copper, one of our most important minerals, is found in many parts of the world. One of the major sources of Copper is the so-called porphyry ores such as the large deposits in the west and southwestern United States, Mexico, South America and Europe.. Porphyry ores, with copper occurring in the form of …
Bulk copper-moly concentrate goes to a thickener prior to treatment in the molybdenum plant. Flotation tailings go to tailing thickeners and roughly 70% of the process water is recycled. The concentrate slurry is piped via Salamanca and Illapel to the purpose-built port of Los Vilos (Punta Chungo) where it is dewatered for shipment.
Hindustan Copper Limited (HCL), a public sector undertaking under the administrative control of the Ministry of Mines, was incorporated on 9th November 1967.

(green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide (FeS), and some heavy metals. Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into
