Gold Project Flowsheet Design | SRK Consulting
It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits left that contain ores ...

Mining & Processing
Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately 180 microns.
Designing gold extraction processes: Performance study of a …
Eventually, the constructed CBR tool should serve gold processing experts in the initial stages of flowsheet design by providing new ideas and possibly a second opinion. The real benefit of the automated decision support system is that it does not exclude any processing methods merely due to human biases, such as familiarity with …
