摘要
某金矿石氰化尾渣浮选精矿难浸,在<37μm占99.5%的磨矿细度下氰化浸出24h,金的浸出率仅有3.95%。采用常温常压碱性强化预氧化工艺处理后,金的浸出回收率提高到85.85%,炭吸附率99.62%。
The floatation concentrates of cyanidation tailings was very refractory, for which the dissolution of gold by NaCN for leaching 24 h under the grinding size of 〈 37 μm of 99.5 % was only 3.95 %. After the preoxidation of intensified alkaline leaching under normal temperature and pressure, the dissolution of gold by NaCN was enhanced to 85.85 %, and the adsorption recovery by activated charcoal was 99.62 %
