Abstract

The high-grade ore produced from the deep ore body of Sanshandao Gold Mine differs significantly from the grade of the produced ore. For the efficient recovery of the deposit, the BPMA process mineralogical analysis system is used to analyze the ore. The main gold minerals are natural gold and silver gold, with an average particle size of 8.18 μ m. Gold deposits mainly coexist with pyrite. By adopting a single optimization, one rough selection, two sweeping and one concentrate flotation process, and increasing the amount of collector by 30g/t, a gold concentrate with a yield of 15.15%, a gold recovery rate of 98.08%, and a gold grade of 54.45g/t was produced. The gold grade in tailings was 0.19g/t, achieving efficient recovery of gold from high-grade ores.
