Hello recently, I am working on processing of a gold bearing mixed oxide-sulfide copper ore (Av. Cu; 0.80 & Av. Au; 0.2ppm). After some research and testing different methods, I found Controlled Potential Sulphidisation (CPS) Flotation as the most effective & practical method on similar ores (E.g., Kanmantoo, Australia & Kansanshi, Zambia).

The objective of the Rentails Project is to re-process the estimated 22.5 Mt of tailings at an average grade of 0.44% tin and 0.23% copper from the historical processing of tin ore. The current tailings dams have a Mineral Resource containing approximately 104,000 tonnes of tin and 53,000 tonnes of copper (refer to ASX announcement dated 30 ...

Enargite (Cu 3 AsS 4) is an important copper mineral due to the amount of copper it contains and, also, the detrimental environmental impact associated with its arsenic content [1,2,3].High financial penalties are imposed by smelters to treat copper concentrates containing greater than 0.2% of arsenic and the rejection limit for smelters is 0.5% of arsenic [].

Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.

Since the emphasis in ibis flowsheet is usually the recovery of copper at a high grade, pyrite, when present, is depressed, and gold recovery is not optimum. An alternative to this flowsheet is shown in Figure 11. This is a bulk sulphide~ flotation flowsheet followed by a regdw prior to the separation of the copper and pyrite.

Detailed chemical assays were done on the copper concentrates. • Copper-gold breccia flow sheet development – G&T: this was an extension of the flow sheet confirmation and included examination of the following:

The most effective method of isolating the Cu minerals is froth flotation. This process causes the Cu minerals to become selectively attached to air bubbles rising through a slurry of finely ground ore in water (Fig. 1.4).Selectivity of flotation is created by using reagents, which make Cu minerals water repellent while leaving waste minerals wetted.

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of …
