摘要
江西东北部某金矿石主要金属矿物为黄铜矿、黄铁矿、砷黝铜矿,常规氰化难浸,金精矿浸出率仅40.34%,进行了滚瓶、引入磁场强化低氧细菌预处理及磁场强化氧化渣浸金等浸金试验研究,金精矿金浸出率获显著提高,达93.21%。
Main metallic minerals are chalcopyrite, pyrite and tennantite in a gold ore from northeast Jiangxi province.Its conventional cyanidation is difficult.The gold concentrate leaching rate is only 40.34%. The research with rolling bottle, hypoxia biooxidation intensified by magnetic field and leaching gold from biooxidation leavings intensified by magnetic field was carried out. The gold leaching rate is enhanced to 93.21%.
