Apr 30, 2020· Yetminingthe ore is just one stage in a long and complexgold mining process. Long before anygoldcan be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract andprocess…
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 gold migrates to a negatively charged electrode (cathode), where it is restored to a highly pure metallic state, leaving the impurities as a separate solution or residue.
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where thegoldand silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb thegoldand silver. This process removes 93% of thegoldand 70% of the silver.

The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks.

A simplifiedprocess flow diagram PDF(58 KB) is attached. ( Download Acrobat Reader ). The gold plant comprises facilities for crushing, grinding, flotation, pressure oxidation (POX), counter current decantation (CCD) washing, neutralisation, carbon-in-leach (CIL) cyanidation and tailings disposal.
Copper Mining&Extraction Process FlowChart. This flowchart made of machinery icons explains or expresses in simple but clear terms the step of theCopper Miningand CopperExtraction Process. Starting from either open-pit or undergroundminingand using a different relevant treatment method for oxide or sulphide copper mineral (ore).
At the processing plant, gold and silver are extracted from the ore. The processing plant alternates between treating ore from the Martha Mine open pit and from the Favona underground mine. Ore processing consists of the following stages: crushing and grinding of the ore.
The process flow sheet at Newmont Boddington Gold (NBG) comprises primary crushing, closed circuit secondary and tertiary crushing using High Pressure Grinding Rolls (HPGR), ball milling and hydro-cyclone classification to generate a milled product with a P 80 of 150 µm. The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters.
The Millerprocessuses gaseous chlorine to extract impurities whengoldis at melting point; impurities separate into a layer on the surface of the molten purifiedgold. The Millerprocessis rapid and simple, but it producesgoldof only about 99.5 percent purity. The Wohlwillprocessincreases purity to about 99.99 percent by electrolysis.
