Abstract

A gold concentrator mainly processes quartz vein ore and altered rock ore. The average tailings grade in flotation production is about 0.13 g / t, and the recovery rate is about 90%. In order to further improve the production index, the process mineralogy detection and flotation test of the two ores were carried out. The test process completely simulated the on-site production process, which was a one-stage roughing + two-stage scavenging process, and the collector was isoamyl xanthate. The test data and experimental data show that the gold-bearing minerals in altered rock ore are finely disseminated, and the composition of sulfide minerals is more complex than that of quartz vein ore. The optimum grinding fineness of quartz vein ore is 45%, the dosage of collector is 80g / t, and the index stability is good. The optimum grinding fineness of altered rock ore is 60%, the dosage of collector is 100g / t, and the dosage of collector and grinding fineness are insufficient, which will lead to the obvious deterioration of flotation tailings and recovery index.
