The magnitude of p suggests that densification, i.e. compaction of the ore particle bed, results in a slight increase in the spacing of solution flow channels but a large increase of the ...
Copper production begins with the extraction of copper-bearing ores in mining or recycling of scrap metal. The ores are processed into copper concentrate, which can be further treated onsite or sold to a smelter. The figures below represent global production and trade of copper contained within ores and concentrates (ICSG, 2015).
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, …
