Copper Mining and Processing: Processing Copper

View PDF Download PowerPoint Oxide and sulfide ores undergo different processes to be purified into 99.99% pure copper. Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.

Gold-Copper Ores ScienceDirect

2016-1-1  Each 1% of reactive copper will consume ∼30 kg/t of cyanide (Drok and Ritchie, 1997), but the Lower and Booth (1965) data show that ores that contain copper sulfide minerals will consume significantly greater amounts of cyanide up to 51.5 kg/t per 1% of reactive copper for covellite, due to the formation of thiocyanate and cyanate in addition to copper cyanide.

Colourimetric determination of copper ore

Concentration Cu = (5/124) x (1000/100) = 0.4 M. The two concentrations should be the same. However, this calculation works only approximately because ‘basic’ copper carbonate also contains an equimolar amount of copper hydroxide and some water. It should be stressed that copper ores are seldom as concentrated as this.

Extraction of copper from its ore

2021-7-20  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.
