摘　　要：本文概述了氨性氧化-氰化法处理含砷难浸金矿的扩大实验结果．对于含有砷、锑、汞、碳的丹寨金精矿，其金品位为17．6g／t，金的氰化率可达84％与小型实验结果相符．A scaled-up test of the ammoniacal catalytic oxidation and cyanidation process was described in this paper. 84% of gold extraction was achieved for the gold concentrate containing As, Sb, Hg, C and 17.6 g/t Au. This result was consistent with the laboratory test.
