摘　　要：黔西南某高砷金矿中金的品位为3 g/t～30 g/t,砷的质量分数在8%～18%范围变化。金呈细粒和微细粒的形式存在,部分金为硫化物,脉石矿物包裹。金的氰化浸出率为50%～60%。砷金矿与催化溶液参与化学反应后,在选择条件下,金的氰化反应浸出率为82%～91%。使得金矿有较好的经济效益和社会效益。The content of gold of a certain gold ore containing high content of arsenic is 3 g/t^30 g/t,and the gold ore contains 8%~18% arsenic in Qianxinan.The most gold is exists as fine particales and micro-fine particales,the other is wrapped in sulphide and gangue minerals.The gold cyanide leaching rate was 50%~60%.If adding auxiliary ageng in gold ore containing high content of arsenic,the gold cyanide leaching rate is 82%~91%.It makes the gold ore have great economic benefits and social benefits.
