Extraction Of Copper Mining, Concentration, Smelting

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of

Chalcopyrite Wikipedia

Chalcopyrite (/ ˌ k æ l k ə ˈ p aɪ r aɪ t,-k oʊ-/ KAL-ko-PY-ryt) is a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the stone formula CuFeS 2.It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale.Its streak is diagnostic as green tinged black. On exposure to air, chalcopyrite tarnishes to a variety of oxides, hydroxides

Extractive Metallurgy of Copper ScienceDirect

Hydrometallurgical extraction accounts for about 4.5 million tonnes of cathode copper per year (about 20% of total primary copper production). Most of this is produced by heap leaching. Heap leaching consists of trickling H 2 SO 4 -containing lixiviant uniformly through flat-surfaced heaps of crushed ore, agglomerate, or run-of-mine ore.

Extraction of copper is done using copper pyrites. After

Extraction of copper is done using copper pyrites. After roasting, the ore is mixed with silica and coke and then smelted in a blast furnace. The matte obtained from the blast furnace is charged into a silica-lined converter. Some silica is also added, and a hot air blast is blown into the mixture to obtain blister copper, which is purified by electrorefining. <br> The stone formula of

What is the role of silica in the extraction of copper

Ores of copper contain iron oxide as an impurity. Silica reacts with iron oxide and forms iron silicate, which is removed as slag. In the smelting process such stone reactions are taking place: 1) Oxidizing of the copper pyrite: 2 CuFeS2 (s) + 3 O2 (g) → 2 FeO (s) + 2 CuS (l) + 2 SO2 (g) 2) Conversion of iron oxides and sulfides into molten slag: FeO (s) + SiO2 (s) → FeSiO3 (l) 2 FeS (s
