The principal copper ore mineral is chalcopyrite (CuFeS 2), 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).Unlike the system for lead, the copper and Cu 2 S melts are nearly immiscible ...

After ore sorting and grinding, used in both types of ore, the main technique used for concentration of sulfide ores is froth flotation followed by smelting and refining (pyrometallurgical process) while in the case of oxide ores (and some low grade sulfide ores) a heap leaching process is combined with solvent extraction and electrowinning (SX-EW) (hydrometallurgical process) .

The two zoning sequences, beginning nearest the source of the metals, are: in hydrothermal deposits, Fe—Ni—Sn—Cu—Zn—Pb—Ag—Au—Sb—Hg, and in sedimentary deposits, Cu—Ag—Pb—Zn. A zoning sequence represents the natural order of increasing solubilities of the metallic sulphides and other minerals in ore-forming solutions.

Ans: Ores are the minerals from which metal is conveniently and profitably extracted. There are mainly four kinds of ores like Ores Oxides; Ores Carbonate; Sulphide Ores; Ores Halides. Most metals are found in nature in a combined state, owing to their high reactivity. Metals found in a combined state in the earth's crust are known as minerals.

Unlike ores these minerals are not limited only to metals. Many clay minerals like kaolinite or bentonite are used in construction industry, calcite is used in cement production, feldspar and quartz are major part of ceramics, zeolites are used in construction materials and chemical industry etc. Economically viable accumulations of these minerals are called mineral resources .

Copper, gold, silver, platinum, and meteoric iron are the only metals found in their native state. However ∼90% of copper comes from sulfide ores. Most copper ores contain 0.5% Cu or less, iron being the principal metallic impurity. The ores are ground to a fine powder and concentrated (normally by floatation) to 20–25% Cu.

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 sulphide just like in blast furnaces calcium carbonate is added as a flux to create the slag.
Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis ( electrowinning ) for low grade ores, or by the carbon reduction method of smelting for higher grade ores.
