CHILEAN COPPER MINING COSTS

AVERAGE COPPER MINING GRADES CHILE VS WORLD • Average Ore grades of the sulfide line have decreased similarly (27%), Chile and the World. • Ore grades of the oxides line in Chile are lower than the world average. • There is a depletion of oxidized resources in Chile, which will mean 66% lower production of SXEW hodes by 2027.

From Ore to Finished Product

7. Sulfide Ore Refining. The final step in processing sulfide ore copper from the smelter is to make high purity copper hodes. 8. Copper Products Many Uses. Copper hodes are pure copper produced from the processing of copper ores. However, hodes are not in the final form of usage as copper materials. 9.

Modelling future copper ore grade decline ...

01/02/2014 · As copper ore grades decline, the environmental impacts of primary Cu production will generally increase, along with other associated costs (Norgate and Haque, 2010). LCA studies show that the level of this increase is dependent on the type of processing utilised to produce Cu ( Alvarado et al., 1999, Norgate and Haque, 2010, Norgate and ...

Electrorefining of Copper

Firerefined copper is adequate for noncritical appliions such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage

THE GEOCHEMISTRY OF COPPER LEACHING

12/03/2012 · The ore and gangue are composed of discrete mineral species. Each mineral species has its own unique dissolution kinetics and solubility in the leach solution. The degree to which the ore and gangue minerals are soluble in the leach solution and the rates at which they dissolve determine copper leach kinetics and acid consumption.

steel ("blanks"). Similar to the sulphide ore refining process, an electrical charge is applied to the liquid, causing the copper to attach to the sheets. Over approximately 10 days, the starter sheets fatten to a width of centimetres, forming percent copper hodes. This process is known as "electro winning".
