Mining Milling - Centerra Gold

Two separate carbon-in-leach (“CIL”) circuits recover the gold from the re-ground concentrate and from the flotation tails, with final gold recovery accomplished by electrowinning and refining. The mill was originally designed with a capacity to process 4.8 million tonnes of ore per year, but the actual mill throughput in 2011 was approximately 5.7 million tonnes per year.

Hashing (extraction/recovery) ... transforming commonly refractory gold in sulphides to ‘free-milling’ gold, behaving in a similar fashion to gold associated with quartz. Gold:sulphur ratio (GSR) Refractory ores are typically treated by flotation and the resulting flotation concentrate may be sold directly to a smelter (common for example in China) or subjected to downstream processing by ...

9 Step Process for Discovering, Mining Refining Gold

Step #6 – Mining samples and determining processing. Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique. Step #7 – Processing (on-site) Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes ...

Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers ...

Mining : What Is Gold Mining? How Is Gold Mined?

Gold is mined using four different methods. Placer mining, hard rock mining, byproduct mining and by processing gold ore. Placer mining. Placer mining is the technique of extracting gold accumulated in a placer deposit. Placer deposits are composed of relatively loose material that makes tunneling difficult, so most extraction methods involve water or dredging. Panning. Gold panning is mainly ...

The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the ...
