Copper Flotation Equipment For Gold Copper

the majority of large scale coppergold ores is low typically around 1 2 gt34. Flotation is the principal method of pre concentration for copper and gold56. 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 economically important7.

Crushing To Floatation Circuits Copper Gold

Ridgeway Gold and Copper Mine, New South Wales - Mining Technology. The grinding circuit comprises a 6.5MW SAG mill and 6.5MW ball mill. Using similar processes to the adjacent Cadia Hill concentrator, gold and copper are recovered in a conventional floatation circuit to produce a copper concentrate containing elevated gold levels.

Separation efficiency improvement of a low grade copper

The recovery of gold-containing 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

Jan 01, 2016Jan 01, 2016Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold

FLOTATION of GOLD

Gold itself is a rare metal and the average grades for low grade deposits vary between 3 and 6 p.p.m. Gold occurs predominantly in its native form in sili-cate veins, alluvial and placer deposits or encap-sulated in sulRdes. Other common occurrences of gold are alloys with copper, tellurium, antimony, selenium, PGMs and silver. In massive

Gold Flotation

Jul 13, 2016Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold. Copper sulphate is frequently helpful in accelerating the flotation of pyrite and arsenopyrite.

Extraction of Gold by Flotation Process

Nov 11, 2019Nov 11, 2019(2) Extraction of gold by flotation process is also used to process polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-bismuth, and gold-copper-lead-zinc-sulfur ore. For this type of ore, the flotation process can effectively identify and extract various gold-bearing sulfide concentrates, which is conducive to the comprehensive

Flotation is the principal process for pre-concentration of the copper–gold minerals for subsequent smelting treatment. Gold recovery, although important, is not always considered when optimizing the copper circuit.
