Abstract: Gold and antimony are of great importance to the national economy.To achieve efficient and comprehensive recovery of gold and antimony from a gold-antimony deposit while reducing environmental pollution,a study on process mineralogy and flotation experiments was conducted.The results of the process mineralogy study showed that the ore has a gold grade of 2.16 g/t and an antimony grade of 0.67 %,both of which are of recoverable value.The main gold minerals are native gold,electrum,and silver-gold telluride,while the primary antimony mineral is stibnite,both showing good floatability.The flotation test results indicate that using the combined gold-antimony bulk flotation followed by separation of gold flotation,with BK526 as an environmentally friendly inhibitor for gold-antimony separation,produced an antimony concentrate with a grade of 57.31 % and a recovery rate of 87.25 %,and a gold concentrate with a grade of 45.34 g/t and a recovery rate of 82.28 %,achieving efficient and environmentally friendly flotation separation of antimony and gold.
