摘要
利用微波的加热特性 ,通过条件试验确定 ,在 45 0℃用微波处理 5min ,可使某金矿的金精矿氰化浸出率由 74%提高到 90 %以上 ,使现场金精矿氰化渣的氰化浸出率达到86 %以上。试验结果表明 。
By using the heating feature of microwave, it has shown from condition tests that the gold leaching recovery can be improved from 74% to more than 90% if the gold concentrates is treated for 5 minutes in a microwave oven at 450℃. Therefore, the gold leaching recovery of cyanide residue of more than 86% can be obtained in leaching plant. The results indicate that microwave pretreatment to packaged gold by pyrite in gold ores has a glory prospect.
