Extraction of Copper from Copper pyrite | Grade 12 Science
The principal ore of copper is copper pyrite and copper is extracted from this ore The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized The ore being sulphide ore is concentrated by froth floatation processCopper oxide can be reduced to copper using hydrogen This reaction is usually done as a large scale demonstration, but this microscale version can be done by students This can be used to show the relative positions of copper and hydrogen in the reactivity series and can also be used for percentage yield type calculationsMicroscale extraction of copper | Resource | RSC Education

Mining in Zambia Wikipedia
Research by the Overseas Development Institute on the taxes and fees in the Zambian mining sector during privatisation in the late 1990s and the subsequent boom in copper prices reviewed the taxes and fees for mining and compared it internationally for royalties and corporate income tax in other major mining countries There were significant differences between countries in how these taxes areCopper is usually found in nature in association with sulfur Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of lowgrade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copperCopper Statistics and Information USGSgov
