LEACHING OF COPPER CONCENTRATES
copper oxides have been in common use for some time. Prior to the development of the Sherritt-Gordon process for nickel and cobalt in which copper is recovered as high grade copper sulfide, copper sulfides were economically recovered in a hydrometallurgical process only during the leaching of waste dumps. .

Flotation Process Development and Assessment
During the plant survey the copper rougher circuit recovered about 60% of the copper, 20% of the lead and 5% of the zinc into the rougher concentrate. Most of the remaining copper and lead was recovered into the scavenger concentrate. Better than 95% of the copper sulphides in the flotation feed were present as chalcopyrite.
