Geothermal energy could be used to enhance copper and molybdenum recovery in mineral flotation by increasing the kinetics of the flotation process. In another approach, geothermal energy could be used to heat the leaching solution which might permit greater copper recovery using the same residence time in a tailings leach facility.

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal.

Copper processing Copper processing Ores Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

Copper has been mined intermittently at Gunpowder, north of Mount Isa, since 1927. Most ventures have had some initial success but fluctuating copper prices, the small-scale of the operations and the remoteness of the site led to closures or sale.
