The first objective of Mineral Processing and Extractive Metallurgy is to remove the Mineral as soon as freed and as coarse as possible” is the first rule in treating complex ores. Ores containing two or three metals have been satisfactorily treated for a number of years. Today, however, ores containing as high as four, five … Read more
Solvent extraction, the process of extracting a specific metal valve from a solution to concentrate and purify that metal is a multistage process involving liquid ion exchange. In the first stage the metal value, in this example copper, exists in the aqueous leachate as an copper ion. The aqueous leachate is mixed with a organic … Read more
