Outline
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.
