The Extraction of Copper - Chemistry LibreTexts

Jun 07, 2021  Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper

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.

EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper.

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, the ore must usually be beneficiated (concentrated).

Copper Mining and Production Processes Explained

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
