Copper Leaching Practices
Several minor methods of leaching presently are used to recover copper from mixed oxide-sulfide ores or from the slime fraction obtained from crushing oxide ores used in vat leaching. These methods are referred to as leach-precipitation- flotation (LPF) and slime leaching, respectively, and are described in the following sections.
