Copper Flotation | Eriez Flotation Division

Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.

Flotation of gold and gold-bearing ores - PDF Free Download

The concentration of gold in the majority of large-scale copper/gold ores is low, typically around 1-2 g/t3,4. Flotation is the principal method of pre-concentration for copper and gold5,6. Thus, porphyry copper ore concentrators are designed with the goal of maximizing copper recovery and grade; however, gold recovery as a by-product is also

copper with gold ore flotation processing

Optimisation of gold recovery by selective gold flotation for copper-gold-pyrite ores. ... Abstract. Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the ...

gold copper ore flotation plant sf037 - plaastoe.co.za

Free gold flotation fundamentally is not possible because gold is a noble element which means it is a chemically nonreactive metallic. Since sulphide flotation collectors chemisorb to the target mineral surfaces, because noble metals do not react, collector adsorption on a pure gold surface is not possible.
