针对某些粘土或细泥含量高的矿物难于进行渗滤浸出的问题,美国矿务局研究出一种制粒堆浸法,并已在工业中投入应用。其方法是:先将粘土或细泥含量高的矿石与一定数量的粘结剂相混合,用10～12％的水或氰化物溶液润湿矿石,然后制粒,使细泥相互成团或使其粘结到粗粒表面,经过固化得到一定强度的团粒。粘结剂可用水泥或石 For some clay or fine mud content of minerals is difficult to leachate leaching problem, the United States Bureau of Mines developed a granulation heap leaching method, and has been put into industrial applications. The method comprises the following steps: firstly, the ore with high content of clay or fine mud is mixed with a certain amount of binder, and the ore is moistened with 10-12% of water or cyanide solution and then granulated to make the fine mud into lumps or So that it is bonded to the coarse surface, after curing to obtain a certain strength of the pellets.
