摘要
对高龙金矿石进行了超细磨小型搅拌氰化试验研究(主要处理矿石中近20％的包裹金),试验结果表明与常规小型搅拌氰化试验相比,超细磨的应用使浸出率提高了0.86～1.43个百分点。如每年处理20万t矿石:井下供矿量占85％,龙爱供矿量占15％;井下矿石品位4.94g/t,龙爱矿石品位2.19g/t;一年可为公司增产黄金12kg左右,去掉超细磨所增加的成本,一年可为公司增效20～30万元左右(此数据为较粗略计算,原矿品位据技监部2001年年终报表)。
The ultrafine grinding mini cyanide leaching experiment study on Gaolong golden mineral (the 20% is including gold). The result index: the leaching rate increase 0. 86 % ~ 1. 43 % compareing the method of convention mini cyanide leaching experiment. If processing amount every year is 20 hundred thousand mine, feeding mine from underground is 85%, the ore grade is 4. 94 g/t; feeding mine from Longai is 15% , the ore grade is 2.19 g/t, the increasing output of gold is 12 kg, deducting the increasing of cost, the increasing benefit every year is about 20~30 hundred thousand yuan.
