The process of leaching sulfide gold ore using the Poster thiourea method, the non-cyanide gold extraction method, and the heap leaching gold extraction process

The process of leaching sulfide gold ore by Poster thiourea method, non-cyanide gold extraction method, and heap leaching gold extraction process
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, gold ore processing equipment generally directly uses gravity separation to recover most of the gold, and then further uses mercury amalgamation or shaking tables according to the nature of the gold ore. Recycle gold and other heavy metals.
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, gold dressing equipment is generally Using the gravity separation method, a rod mill is used to grind the gold ore to the point where the coarse-grained gold is separated from the gangue, and then enter the jig to recover the coarse-grained gold as early as possible. There are also multi-stage grinding and multi-stage sorting processes. The purpose is also In order to recover coarse gold as early as possible and avoid the loss of gold after over-grinding.
