refine process concentration copper and gold slurry

at about 11.0. At a slurry concentration of 50% solids, the slurry passes through a series of agitated mixing tanks with a residence time of 24 hours. The gold bearing liquid is then separated from the leached solids in thickener tanks or vacuum filters, and the tailings are washed to remove gold and cyanide prior to disposal

Copper concentrate is smelted and converted to metallic copper, which allows it to attain forms that can be submitted to further refining, more than 99% pure, as in copper anode and copper blister. The main application of copper anode is to use it as raw material in the process of electrolytic refining, to produce the electrolytic refined

Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury, by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel, or by grinding the ore in a ball, rod, or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury

Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold does at temperatures equal to or greater than the melting point of gold

According to the conventional grinding-floating process, the grit is further sorted to obtain a concentrate with a copper grade of 18% and a gold grade of 6.88g / t. The comprehensive recovery rate of copper and gold (relative to the original ore) increased by 2.04% and 1.85% respectively. Conclusion
