| Abstract: |
| Cyanidation is one of the effective ways of gold production. The factors influencing the cyanidation leaching separation of gold ore that Gold grade is 3.10g/t, the particle size of gold is coarse grain and the gold mainly exists in gangue minerals quartz and feldspar were studied and the optimal conditions of the process of cyanidation leaching separation were determined to be：with baking temperature of the grinding fineness-0.050mm90.00%, lime dosage 3kg/t (adjusted pH11~12), sodium cyanide2kg/t, pulp concentration40%, extraction time24h,gaining the leaching rate of gold96.13%. |
