Copper Ore Processing Methods
Copper Ore Processing Methods

Copper Ore Processing Methods. The four major steps in the production of marketablecopperare mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining.

Theprocessused to treat sulfidecopper oresbegins at the mine site, where thecopper-bearingminerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage ofcopper increasesas theoreis refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams.

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas.

Reduction of Metals (ExtractionfromOre) - A-Level Chemistry

Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is therefore reduced. The carbon gains oxygen, and is therefore oxidised.
