Zinc precipitation recovery; Carbon adsorption recovery may include the following alternatives: Carbon-In-Pulp (CIP) Carbon-In-Leach (CIL) Carbon-In-Column (CIC) Refractory ore processing methods almost always serve only one purpose, to treat ores that will not liberate their values by conventional cyanide leaching. The refractory ore treatment
