砂金含量很低,一般0.2 ~ 0.3g/m大学;砂金材料的粒度构成广泛,煤矸石的最大尺寸比砂金大几千倍的最小尺寸,在当选后需要分级的金的石块和砾石,把选出的矿石量;精矿产量很低,一般0.01% ~ 0.1%;选矿率极高,可达几倍甚至几千倍成千上万;重力浓缩后需要重复选择过程中,为了获得一个砂金和合格的重矿物精矿;强力胶砂金矿、冻土冻块黄金输出层必须破碎的作用以前在黄金回收率。 白砂金矿的选择原则,结合重力最大的黄金原矿石回收率和其相关的重矿物,然后由重力、浮选、磁选、电融合、分离,将金和重矿物相互感应,分别达到康复的目的。
Placer gold content is very low, generally 0.2 ~ University of 0.3g/m; granularity of placer gold materials constitute a wide range, the maximum size of the coal gangue than sand JINDA thousands of times the minimum size, after the election needs graded gold stone and gravel, to choose the amount of ore; concentrate production is very low, generally 0.01% ~ 0.1%; mineral processing rate is extremely high, up to several times and even thousands of thousands of times; gravity concentration need repeated selection process, in order to obtain a placer gold and qualified heavy mineral concentrates; glue sand gold, frozen frozen gold output layer must be broken before in the gold recovery rate. The selection principle of white sand gold, combined with the largest gravity gold ore recovery rate and its associated heavy minerals, followed by gravity, flotation, magnetic separation, electrostatic fusion, separation, gold and heavy mineral mutual induction, respectively to rehabilitation.
