摘要
介绍了含锰铁的银矿石的矿物学组成及工艺矿物学特点。矿石经焙烧、焙砂湿法分步浸出银、铅、锌的试验结果表明,银、铅、锌浸出率分别为93.31%,96.24%和96.50%。
Mineral comstituents and technological mineralogical characteristics of refractory silver ore containing manganese and iron are introduced. The ore is roasted first, and then silver, lead and zinc are leached from roasted product by multiplestep wet process. The experimentation results show that leaching rate of silver, lead and zinc is 93.31%, 96.24% and 96.50%, respectively. They are higher than that of direct leaching.
