据苏联克拉斯诺雅尔斯克有色金属学院的资料,该学院在实验型毛细—薄膜分离器上对4种产物(浮选尾矿、氰化处理尾矿、水力旋流器的溢流和浮选精矿)进行回收细粒金的试验。为了分选各种粒度的浮选尾矿,他们推荐使用包科圆锥分级机或水力旋流器进行预先水力选级。对氰化尾矿样品进行闭路试验结果表明,可获得含金量达680g/t的产品,金回收率为的产品89.99％。在这种条件下,溢流中含金量
According to the Krasnoyarsk Institute of Nonferrous Metals, the institute conducted experiments on four types of products (flotation tailings, cyanidation tailings, hydrocyclone overflow and floats) on experimental capillary-membrane separators Selected concentrate) for the recovery of fine gold test. In order to sort flotation tailings of various sizes, they recommend the use of Baotou cone classifier or hydrocyclone for pre-hydraulic classification. The closed circuit test of the cyanide tailings samples showed that the product with the gold content of 680g / t and the gold recovery rate of 89.99% were obtained. Under these conditions, the gold content in the overflow
