Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations,...
Copper Mining and Processing: Processing of Copper Ores ...
The copper concentrate is first sent through the smelting furnace to be heated up to 2,300 °F and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities.

Handling guide for copper concentrate in bulk
Although copper occurs naturally in a pure state, it’s primarily mined from the minerals chalcopyrite, bornite, and malachite. Copper ore is extracted form the earth, then converted into copper concentrate, which is then roasted, smelted and converted into refined copper.
Management of copper pyrometallurgical slags: giving ...
The average composition of final copper slag corresponds to 30–40 % iron, 35-40% silica, less than 10 % of alumina and calcium oxide and copper content is less than 1%, depending on the method used to clean the final slag of the pyrometallurgical process.

MINING TO SMELTING - GOLD/COPPER CONCENTRATES IN …
Copper concentrate smelting is a large scale, intensive process consisting of four stages: sulphur in the sulphide minerals is “burnt-off”; the metals are melted to form a “matte” and the waste material forms a “slag”; copper in the matte is electro-refined to copper metal; and the gold/silver is refined to doré.
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)
Recovery of Copper from Reverberatory Copper Slag and ...
concentrate, various mining operations have initiated the recovery of copper from dumped slag. The typical process uses crushing, milling and flotation. These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard slag.
Recovery of Cobalt and Copper from Nchanga Mines Slag ...
most of the copper smelting slag contains certain amount of copper, cobalt, iron, aluminium and silica [1]. These metal losses to slag occur as a result of mechanical entrapment of the particles or floating of unstable droplets of matte as well as the physical-chemical solubility of the metals in slag in the oxide and sulphide forms [2, 3].
