| 摘 要： | 某低品位金矿石类型低硫半氧化微细粒浸染，常规选矿方法难以回收其微细粒金．工艺矿物学显示其脉石包裹金占总金的23．05％，采用全泥氰化浸出、细磨浮选等工艺回收率低．试验结合工艺矿物学研究，采用超细磨技术，使连生体得到充分解离，联合全泥浸出提金工艺，得到了浸出率为94．33％的良好指标．与常规氰化浸出相比金浸出率提高了近25％．

| Abstract: | A low-grade gold ore is characterized by low sulfur, semi-oxidation and micro fine impregnated structure. Conventional mineral processing technology failed to recover the micro-fine gold. Process mineralogy shows that 23.05 % gold is encapsulated in gangue. The recovery is low when using all-sliming cyanidation or fine grinding-flotation. Based on the process mineralogy, a fine gold recovery of 94.33 %, which is almost 25 % higher than conventional cyanide leaching is obtained through superfine-grinding technology. |
