摘要
随着黑矿资源的枯竭,精矿中复杂矿的比率可增至10%以上,所谓复杂矿就是指按一般黑钨精矿碱压煮工艺分解,其分解率在(94～95)%的钨矿。通过调整工艺参数,要使疑难矿的分解率提高(4～5)%,具有明显的经济效益和社会效益。
With the exhaustion of wolframite sources,the rate of complex ore in concentrate can increase to over10%.So-caued complex ore refers to decomposition according to usual caustic autoclave proass of wolframite concentrate and its decomposition rate is(94-95)%.Adjusting process parameters can make the decomposition rate of complex ore increase(4-5)%,which is of obvious economic and social benefits.
