Copper Ore Old Method With Gold Extraction-GOLD MINING


Gold extraction - Wikipedia

If the gold can not be concentrated for smelting then it is leached by an aqueous solution: . The cyanide process is the industry standard.; Thiosulfate leaching has been proven to be effective on ores with high soluble copper values or ores which experience preg-robbing: the absorption by carbonaceous components which preferentially absorbs gold and gold-cyanide complexes.

Heap leaching - Wikipedia

Copper ores The method is similar to the cyanide method above except sulfuric acid is used to dissolve copper from its ores. The acid is recycled from the solvent extraction circuit see solvent extraction-electrowinning SX/EW and reused on the leach pad.

Eliminating Copper from Gold Ore

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite azurite and chrysocolla but these acids have but little effect on sulphide copper .

Treatment of copper-rich gold ore by cyanide leaching .

Therefore ammoniacal cyanide leaching of a copper sulphide-rich high grade gold ore was investigated using Box-Behnken experimental design to demonstrate the significance of main and interaction effects of concentrations of NH 3 NaCN and Pb NO 3 2 on the extraction of gold and copper selectivity and cyanide consumption.

The Extraction of Copper - Chemistry LibreTexts

Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite & 92; CuFeS 2& 92; are converted to copper by a different method from sili e carbonate or sulfate ores. Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of .
