The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining it. The cost of extraction must be weighed against the metal value contained in the rock to determine which ores should be processed and which ores are of too low a grade to be worth mining.

Concentration of the copper(II) sulfate solution by solvent extraction. The very dilute solution is brought into contact with a relatively small amount of an organic solvent containing something which will bind with copper(II) ions so that they are removed from the dilute solution. The solvent must not mix with the water.
Gold refining by solvent extraction—the Minataur™ Process by A. Feather*, K.C. Sole*, and L.J. Bryson* Synopsis The Minataur™ Process (Mintek Alternative Technology for Au Refining) is a novel route for the production of high-purity gold using solvent extraction. Following the successful
