摘　　要：根据沃溪区低品位地表氧化矿矿石的性质特点,通过小型柱浸试验和堆浸工业试验,采用堆浸—活性炭吸附—解吸电解工艺处理该矿石,工艺中采用隐蔽剂以消除砷、锑矿物对氰化的影响,金回收指标较好,经济效益可观。Depending on the characteristics of the low grade oxidized ore on the surface in Woxi, and by small scaled column leaching tests and commercially scaled heap leaching tests, a flowsheet of heap leaching-carbon adsorption-disadsorption and electrowinning was applied, where masking agent was used to reduce the influence of Arsenic and antimonial on cyanidation. Good gold recovery and economic results were achieved.
