It must be borne in mind that, although we study a specific flotation process for copper ores, its oxidized degree can vary within a range. Therefore, the range of copper grades in ...

The Importance of pH in Flotation

Starch is particularly useful in the flotation of native gold in the presence of flocculent gangue slime ; a small amount of the reagent will generally deflocculate the gangue without affecting the gold. ... There are, however, one or two ores containing sulphide copper minerals which need an acid circuit for successful flotation. David August ...

THE TREATMENT OF REFRACTORY COPPER-GOLD ORES …

Activox® is a hydrometallurgical process used to oxidise sulphide concentrates. The process is based on two relatively simple, established unit operations; i.e. fine or ultra-fine milling (UFM) and pressure oxidation under mild conditions. An under-standing of, and ability to control the pulp chemistry during oxidation has resulted in the successful Activox® treatment ( on a …

Copper Gold Sulfide Ore – Flotation & Cyanidation Tests

Grinding the ore to minus 100-mesh gave satisfactory liberation of the minerals. Standard flotation procedure with potassium ethyl xanthate, cresylic acid, and lime produced good-grade copper concentrates with over 85 percent recovery of copper and about 60 percent recoveries of gold and silver.

(PDF) Investigation of flotation parameters for copper recovery …

After plastic flotation, the particle size, the dosages of collectors, frother, and activator were investigated and a copper concentrate assaying 53.5% Cu was obtained at the end of the copper ...
