When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with,Beneficiation process of gold ore - Fodamon Machinery,A modern cyanide mill recovers or extracts 95% to 98% of the gold in the ore. In a cyanide mill, lime and cyanide are added to the ore pulp in the grinding circuit. The lime has several functions: it protects the cyanide from being destroyed by naturally occurring chemicals called cyanicides and improves the settlement rate of the pulp in the thickening stage. Cyanidation (the actual,Coated gold—its contribution to gold losses in gold plant,,placed after the stamp mill screen. It was believed that, using a 6.85 mm square mesh screen and a copious supply of water into the mortar box, a major portion of the gold content of the ore would be freed in its natural state from the ore without further comminution.
