摘要
针对甘肃某矽卡岩型金矿石浸渣金品位偏高、金浸出率低的问题,对含金3.70 g/t的金矿石,进行了预氧化、边磨边浸、助浸剂助浸、富氧浸出等多种强化浸金方案对比试验,获得金浸出率91.08%～92.16%的较好指标。本试验研究对该类型金矿的氰化浸金具有借鉴意义。
Aiming at the problems of high leaching gold grade and low rate of gold leaching of a skarn-type gold ore in Gansu,this paper provides an access to the study of gold leaching rate of 91.08%~92.16%,with the approach of comparing the experimental data of 3.70 g/t of the gold by pre-oxidation,leaching while grinding,leaching aid and by oxygen extraction.The experimental research provides a significant reference for the research of cyanide leaching of gold.
