Gold processing 101. Alan Riles looks at the primary flowsheet selection drivers for gold concentrators. Alan Riles. 07 September 2017. Amidst the general fall in metal prices over the last few years, the gold price has remained comparatively stable in the US$1,000-1,250/oz range. Gold bulls were disappointed that the price did not break ...
inventory of gold bound in the process and ensures good and safe working environment. The process produces fine gold and separates valuable impurities such as platinum group metals (PGM) and silver for recovery and further refining. Atomization of gold doré The feed material received from gold cyanidation plants is high-grade gold bullion bars.

of gold process operating costs. As an illustration, for a gold ore grading 2.3 g/t, a 1% increase in gold recovery generates incremental revenue of about $1/t-ore at a gold price of $1,300/ oz. For cyanide at a price of $3,600/t delivered to a remote mine site, it takes only 0.28 kg/t-ore consumption to equate to $1/t-ore, or 1% gold recovery.

After the gold ore has been removed from the earth using mining equipment, it is sent to a gold processing plant. 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.
Gold extraction Gold ore processing •Generally requires 60 to 90 days for processing ore that could be leached in 24 hrs in a conventional agitated leach process. •Au recovery is around 70% as compared with 90% in an agitated leach plant. •BUT, has gained wide favour due to vastly reduced processing costs.
