摘　　要：马达加斯加Maevatanana矿区矿石工艺类型为石英脉型含金氧化矿石。矿石中硫化物为0.25%,金品位较低,为0.8 g/t。通过提金探索试验表明,采用氰化浸出提金工艺与重选—浮选联合工艺时,其尾渣品位相差不大。综合考虑该地区对环保的要求及经济效益,避免氰化尾渣污染环境,适宜采用重选—浮选联合工艺处理矿石。Gold-bearing ores in Maevatanana Mining District in Madagascar belong to quartz vein type gold-bearing oxide ores. The sulfide in ores are 0.25 %, the gold grade is relatively low at 0.8 g/t. The gold extraction experiments show that tailings grades produced by cyanide leaching or combined process of gravity and flotation differ in narrow range. Taking both environmental protection and economic profits into consideration, the combined process of gravity and flotation that spares cyanide would be the best option for processing.
