Process method for extracting gold and copper from Bosite high-copper gold concentrate, cyanide leaching gold process from copper-containing gold concentrate
The particle size of gold embedded in the ore not only determines the degree of grinding, but also determines the choice of mineral processing method . During the grinding process, when coarse-grained gold is dissociated from other mineral monomers into free gold, it is first recovered by gravity separation or mercury amalgamation. This is of practical significance for improving the flotation and cyanidation in the next step, because coarse gold Gold particles are often difficult to flotate or require a long period of cyanidation to recover.
For the recovery of coarse-grained gold in placer gold mines, gravity separation is generally used directly to recover most of the gold. Then, based on the nature of the gold ore, mercury amalgamation or shaking tables are used to further recover gold and other Heavy metal.
The specific recovery process of coarse-grained gold in placer gold mines is: screening jig amalgamation or screening jig shaker
For the recovery of coarse-grained gold in vein gold mines, gravity separation is generally used. , use a rod mill to grind the gold ore to the extent that the coarse gold is separated from the gangue, then enter the jig to recover the coarse gold as early as possible. There are also multi-stage grinding and multi-stage sorting processes, the purpose of which is also to recover the coarse gold as early as possible. Grain gold to avoid gold loss after over-grinding.
