AGR uses different assaying methods FIRE ASSAY The AGRcertified laboratory engineers use the Fire Assay Method also known as the Cupellation Method to determine the concentration of Gold and Silver A small sample of material has its precious metals chemically separated from the impurities and base metals contained in the materialMore Details
The sulfuric acid leaching stage was studied based on a statistical approach applied to the experimental design Using the PlackettBurman method temperature of the leach solution stirring speed concentration of sulfuric acid and particle size of the ore were selected as the variables that had the largest effect on the experimental responseMore Details
In addition sulfur dioxide is formed from the sulfide oxidation reaction and either converted to sulfuric acid in a traditional acid plant or converted to sulfate from its reaction with carbonate and hematite in the ore and with lime added to the ore these reactions are known as fixation of sulfur dioxideMore Details

1 Introduction Pregrobbing is the phenomenon whereby the gold cyanide complex AuCN 2 − is removed from solution by the constituents of the pregrobbing components may be the carbonaceous matter present in the ore such as wood chips organic carbon or other impurities such as elemental carbonMore Details
21 Leaching Most copper leaching is done by piling broken ore ∼05 Cu into flatsurface 3–10m high 10 4 –10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1–5kg Cum −3More Details
The acid detaches the gold from the rock dust and transports it in the acid seepage fluid in a chemically bound form Subsequently the gold is filtered out of the leach solution by adding zinc dust then washed out of the muddy substrate and finally dried The recovered raw gold isMore Details
