一、流程1.浸出南非锌公司的流程原来是在帕丘卡空气搅拌浸出槽内进行间断浸出的,但是存在着未被浸出的焙砂会生成凝聚物的问题。这种凝聚物是在硫酸锌含量约为10%的焙砂很快加入到浸出液中时生成的。焙砂中的水分,会使硫酸锌成水合物,而这种硫酸锌在颗粒粘结中起着粘胶作用。加快搅拌速率,也不能使这种情况有所

First, the process 1. Leaching South Africa Zinc company’s process turned out to be in the Pachuca air mixing leaching tank intermittent leaching, but there is not leaching of the calcite will generate the problem of aggregates. This agglomerate is formed when calcine is added to the leachate at a rate of about 10% zinc sulfate. The water in the calcine makes zinc sulfate hydrate, which acts as a viscose in particle bonding. Speed ​​up the mixing rate, nor can this be the case
