Copper Ore an overview ScienceDirect Topics

The principal copper ore mineral is chalcopyrite (CuFeS2 ), which is commonly smelted to yield a matte containing ∼50% copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature ( Rosenqvist 1978 ).

Extraction Of Copper Mining, Concentration, Smelting

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper

2015-9-10  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

How copper is made material, used, processing, steps

Concentrating. The copper ore usually contains a large amount of dirt, clay, and a variety of non-copper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is

This indicated that Na 2SO 3 can improve the degree of sulfating at high temperature. One possible reason is that the addition of Na 2SO 3 could prevent the decomposition of copper sulfate. Another possible reason is the exist of some com-
