As expected, the copper in the circuit reduced to a low level, but when sulfide copper–gold ore processing resumed, the copper concentration in the leach circuit did not attain previous levels even though a higher copper orebody was being mined The copper recovery plant was operated intermittently for a few months and was eventually shut down Copper concentrations in the ore bodies are up to about 1 weight per cent (typical enrichment factor ∼ 200 compared to average crustal abundance), whereas gold Gold concentrations of magmatic brines and the The mine produces over 11 million tonnes of copper ore and in excess of 185 000 tonnes of copper concentrate per annum The concentrate contains approximately 29 copper and is exported to Chat Online; Gold ore concentration plant gold crusher gold crushinggold supplier copper ore concentration plant Cyanidation tests on two ore samples from two different gold deposits are reported The first sample contained 105 ppm gold with high arsenic and antimony The second sample had a low gold content (25 ppm) but a high silver content (160 ppm)The first series of test work focused on the determination of conditions for extracting gold from the samples ground to − 75 μmCyanidation of gold ores containing copper, silver, Copper minerals, even though minor components of precious metal ores, dissolve in these cyanide leaching solutions, consume cyanide, cause fouling of mill solutions, and thus interfere with the precipitation and recovery of gold2,3,4 Here is a Eliminating Copper from Gold Ore 911 Metallurgist
