Copper–gold ore processing with ion exchange and SART technology

The ore body is a complex copper-gold porphyry deposit, comprising intermixed oxidized, transition and sulphidic gold and copper-bearing ores. Gold in the sulphide ores is generally not refractory and is recoverable by cyanide leaching, but the secondary copper minerals, which are also cyanide soluble, lead to high cyanide consumptions.

Everything You Need to Know about the Gold Smelting Process

What Is Smelting? Many people confuse gold smelting and melting. While melting entails heating the gold from solid to liquid form before forming gold bars, the smelting process is more complex and involves removing impurities from the gold using a combination of pressure, heat, and several chemicals.

Biogenic sulphide for cyanide recycle and copper recovery in gold

Copper–gold ore processing (higher copper values than gold values) generally involves flotation and smelting. In the latter case, gold credits are obtained from the smelting of the copper concentrate, and if gold reports to the flotation tailings, they may also require cyanidation. A notable and relevant exception to this generalization is ...
