copper gold ore processing

Gold-Copper Ores - ScienceDirect

Jan 01, 2016  Today, flotation is commonly used in the processing of primary copper–gold ores to produce a copper concentrate containing gold as a co-product, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron ...

Gold Refining From Gold Ore to Doré World Gold Council

Sep 03, 2021  In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore ...

Agglomeration Drums in the Heap Leaching Process

Heap leaching, a process by which metals such as gold and copper are recovered from ore, has long been a method of choice in ore beneficiation, with applications growing all the time.. While this process has proven to be efficient, often chosen for its cost-effectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum.

Ore mills generate large amounts of waste, called tailings. For example, 99 tons of waste is generated per ton of copper, with even higher ratios in gold mining – because only 5.3 g of gold is extracted per ton of ore, a ton of gold produces 200,000 tons of tailings. (As time goes on and richer deposits are exhausted – and technology ...
