| 摘 要： | 肃北县黑刺沟金矿属砾岩型金矿，该矿矿石属典型的含砷、硫微细粒难选金矿石。通过各种选矿试验，该矿矿石用全泥氰化法金浸出率低于１７％ ，浮选、焙烧氰化法浸出效果也不好，而用细菌预氧化、碱浸预氧化氰化法效果较好，金浸出率最高可达９２．４％ ，是处理该类矿石较有效的选矿方法。

| Abstract: | Heicigou gold deposit is identified as breccia type gold deposit.The ore belongs to typical As and S bearing microgranular refractory gold ore.Various testings were conducted on the ore and the conclusions are as follows:Gold leaching rate is lower than 17% by all sliming cynidation;Gold leaching effect is poor by floatation and roasting cynidation;Bio preoxidizing cynidation and alkali soaking cynidation get the best results,the highest gold leading rate is up to 92 4%,and they are the effective methods for processing this type of ore. |
