Copper Sulfide Pyrometallurgy

Pyrometallurgy - an overview | ScienceDirect Topics

The pyrometallurgical process is suitable for iron ore, chromite, lead, zinc, copper, tin, and tungsten. Pyrometallurgy follows one or more of the following processes. 13.7.1.1.1 Calcination. Calcination is the thermal decomposition of a sulfide/carbonate ore. The decomposition of calcium carbonate to calcium oxide and carbon dioxide as well as iron carbonate to iron oxide is: CaCO 3 → CaO ...

Chapter 6 Copper Production Technology

Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-

12.3 Primary Copper Smelting

12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg) (1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to ...

Copper: smelting, producing and classification …

Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Copper Mining and Extraction Sulfide Ores

Education Resources Copper Mining and Extraction: Sulfide Ores . It’s hard to imagine a world without copper. We rely on copper for power, lighting, heating, communications, water supply and transport. Copper makes our homes, schools and businesses efficient, comfortable and decorative and it lasts for many years. In this e-source, we’ll look at the ways of extracting copper from the ...

Copper Ore Hydrometallurgy and Pressure …

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal. Hydrometallurgy is advantageous in flexible capacity ...

Pyrometallurgical Process - an overview | …

It has been reported that in the smelting processes from sulfide concentrates for copper production, the slag volume generated reaches 2.2 times of the copper production in average [14]. Obviously, the copper extraction in pyrometallurgy contributes the largest amount of slag among all the nonferrous metals.

Oxygen Pyrometallurgy at Copper Cliff - …

Intensive laboratory and tonnage pilot-plant R&D on the oxygen flash smelting of sulfide concentrates was initiated at the end of December 1945. It proceeded in classical stages: first in two-dimensional stone studies of smelting, using solely sulfur and iron as fuels; then in increasingly large three-dimensional apparatus design and operation. Excellent validating metallurgical and economic ...
