The Extraction of Copper

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(II) sulfate solution. Concentration of the copper(II) sulfate solution by solvent extraction.

Mineral processing

Concentration is defined as the number of moles of a solute in a volume of the solution. In case of mineral processing, concentration means the increase of the percentage of the valuable mineral in the concentrate. Gravity concentration

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

Copper Concentrates

Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity ...

Copper

Copper and nickel are adjacent to one another in the periodic system of elements, with atomic numbers 29 and 28 and atomic weights 63.54 and 68.71.The two elements are closely related and are completely miscible in both the liquid and solid state. Cu-Ni alloys crystallise over the whole concentration range in a face-centred cubic lattice.

MINING TO SMELTING

Copper concentrate smelting is a large scale, intensive process consisting of four stages: sulphur in the sulphide minerals is "burnt-off"; the metals are melted to form a "matte" and the waste material forms a "slag"; copper in the matte is electro-refined to copper metal; and the gold/silver is refined to doré.
