Coppergold ores are significant contributors to the overall world gold production. flotation is the principal process for preconcentration of the coppergold minerals for subsequent smelting treatment. gold recovery, although important, is not always considered when optimizing the copper circuit.

Consequently, gold flotation recovery requires a focus on floating the associated base metals predominantly lead, copper and often pyrite minerals. while lime is often used in base sulphide mineral flotation, because excess lime also tends

The occurrence of fluorine in the coppergold concentrates produced by ok tedi mining limited has provided a series of challenges to metallurgists since 1988. although fluorine is distributed throughout the gangue minerals contained within ok tedi ores, its presence in talc and phlogopite naturally floating fluorosilicates has proven to be the predominate sources of fluorine...

Jul 23, 2014nbsp018332since its discovery, froth flotation has been a major component for the processing of sulfiderich ores, including copper, coal, and refractory gold. in gold mining, froth flotation is used to separate gold from gangue by utilizing golds hydrophobicity. first, refractory gold ore is ground as finely as possible usually so the individual ...

The recovery of goldcontaining pyrite to the copper concentrate is encouraged to achieve a higher total gold recovery provided that a saleable copper concentrate grade is still produced. mineralogical diagnosis of feed and product streams from the copper flotation circuit have shown that the copper bearing minerals are well liberated

The concentration of gold in the majority of largescale coppergold ores is low, typically around 12 gt3,4. flotation is the principal method of preconcentration 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 byproduct is also

Typical applications of flash flotation can be found in gold, silver, platinum and other pgms, lead, copper, nickel, and combinations thereof. it is worth noting that typically flash flotation is not extensively evaluated during a feasibility study and hence it is unknown if it would be
