The copper ore of a copper mine in zimbabwe is mainly copper-bearing pyrrhotite and high-copper skarn ore.The copper grade of the original ore is 1.25, and its iron grade is 30.73.The copper minerals in the ore are mainly chalcopyrite, followed by porphyry, and a small amount of chalcocite, covellite, malachite, etc.
Virtually all sulfide-type copper ores, including chalcocite cu 2 s, chalcopyrite cufes 2 and covellite cus, are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper.

Copper is extracted in large amounts from the earths crust by mining of sulphide ores and also oxide ores.The procedure of copper processing involves mining and transporting.Oxide ores are generally processed through hydrometallurgy- heap leaching, solvent extraction and electrowinning.The sulfide ores are usually processed using the method of pyrometallurgy- froth floatation, thickening.
Read MoreExtracting copper from other ores.Copper can be extracted from non-sulphide 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 sulphuric acid to produce a very dilute copper.
Read MoreAfter this stage the enriched ore now contains about 25 copper by mass and is called copper concentrate.It is valuable enough to ship to other plants and other countries for processing.For example china, germany and japan are major copper producers that use concentrate from around the world.
Read More2 in refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has copper.In these operations some of the copper is oxidized to cuprous oxide and dissolved by the metal bath.

Read MoreCopper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines.The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.
Read MoreAcids are introduced to copper-bearing ore, seeping through and dissolving copper and any other metals, including radionuclides.The liquid that leaches through the rocks is collected.This liquid contains the dissolved copper, known as a pregnant leach solution pls.The copper present in this liquid is collected and later processed.
Read MoreThe price of the ore depends on two things 1 the value of the copper it contains, minus 2 the cost of recovering that copper mostly excavating it from the ground, separating it from the gangue minerals, recovering it as metal, and getting it.

Read MoreT h e year 1917 was a watershed for australian copper mining and particularly for copper smelting.Prior to this time many copper mines were equipped with an on-site smelter, into which high-grade copper ore or a gravity copper concentrate were fed to produce a copper matte with 40 per cent copper for subsequent converting to blister copper 99 per cent copper and refining at centralised.
Read MoreIron ore consists of oxygen and iron atoms bonded together into molecules.To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.
Read MoreCopper ore can be processed to copper concentrate or copper sand after beneficiation.There are many kinds of copper ores, such as pyritum, chalcopyrite, bornite, cyprite, chessylite, covellite and malachite.Copper ore can be used in metallurgical industry and it is the main raw material of metallurgical industry.
