Even the highly toxic cyanidation is an industrial process of gold production, whereas the artisanal miners use mercury for dissolving the gold traces from the collected mud, soil, and rocks. As an estimate, about 140 kg of cyanide and a massive consumption of 700 tons of water are required to produce 1 kg of gold (Mudd 2007 ).

This article will introduce the flow of a CIP gold processing plant: from raw gold ore to gold bar step by step. The main process of the CIP gold processing plant to extract gold from ore and convert it into pure metal can be divided into 6 steps: crushing, screening, grinding, classification, carbon slurry gold extraction and tailings treatment.
The operation consists of a large-scale surface mine, an underground mine, and an adjacent process plant inclusive of an autoclave for pressure oxidation of the ore. Its annualised gold production is split approximately 75% to open pit production and about 25% underground production. Quick Facts: Type: Underground and open pit:
The As pollution status of plants and soil in mine polluted area was evaluated by comprehensive investigation. • The degree of soil pollution was found to have a non-linear relationship with the distance from the mine source, with a high correlation (R 2 = 0.9844).. B. bipinnata, P. vittata and B. nivea are dominant species in As-contaminated …

The typical gold processing plant begins with a cone crusher, to reduce the particle size of the ore. Next, it is loaded on a conveyor belt, where an overbelt magnet removes tramp metal from the gold mining process. The ore goes for preliminary screening, followed by stream sampling, which is a process that uses a hammer sampler.
