Sep 26 2019 · Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw mined state into a purified form for use in many industries Copper is typically extracted from oxide and sulfide ores that contain between 0 5 and 2 0 copper
In the leaching process ensure the fineness of grinding products 200 mesh accounted for 85 95 the pulp concentration accounts for 40 45 then add a certain volume of CNLITE ECO gold leaching agent Make sure the leaching slurry concentration is not less than 0 015 to efficiently leach the gold ore
Extraction of copper from suitable ore by leaching methods is generally assumed to cost less than the combined expense of concentration smelting and refining and experimental data tend to confirm this opinion At the Butte Duluth plant which is handling in excess of 100 tons of oxidized ore daily the copper is said to cost 0 085 per pound
Gold cyanidation also known as the cyanide process or the MacArthur Forrest process is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex It is the most commonly used leaching process for gold extraction Production of reagents for mineral processing to recover gold copper zinc and silver represents
In this study weak acid in the curing and leaching stages of copper ore was incorporated and we analyzed its effect on the dissolution of copper and final impurities The weak acid corresponds to a wastewater effluent from sulfuric acid plants produced in the gas treatment of copper
