Mineral Processing of Kamtor Gold Ore in Kyrgyzstan
摘要
Abstract
To enhance the resource utilization rate of fine-grained refractory gold ores,a combined process of flotation and leaching was studied for the extraction of gold from the Kamator gold ore in Kyrgyzstan(Au 3.07 g/t,Ag 20.40 g/t).The results show that a gold concentrate with a grade of 28.57 g/t can be obtained through closed-circuit flotation,with a gold yield and recovery rate of 8.05％and 72.47％,respectively,and the gold grade of the flotation tailings is 0.95 g/t.Under suitable conditions,the average gold leaching rate of the flotation tailings can reach 83.16％,with a relative gold recovery rate of 22.89％compared to the original ore,and the gold grade of the leaching residue is 0.16 g/t.By adopting the flotation-leaching process,the comprehensive gold recovery rate can reach 95.36％.This method can effectively recover gold from this type of ore.关键词
