Rock Gold Panning Drum Screen

In general, the river pebbles and other large stones in alluvial gold ore do not contain gold at all, but such stones occupy 20 percent to 80 percent of the alluvial gold ore, so in the early stage of alluvial gold washing, pre-screening such waste stones has a very important role in improving the effective working rate of the whole alluvial gold washing production line, so the first process of alluvial gold washing is sieving. Alluvial gold ore sieving can use trommel screen or vibrating screen, if the alluvial gold ore contains more sticky mud, the gold particles are easy to be wrapped by the sticky mud, in order to make most of the gold particles free out, the alluvial gold ore with high mud content must be washed, which is used in the washing machine.



Fine-grained Dipping Quartz Veinstone Gold Ore

As shown above, this gold ore type belongs to the gold ore which is embedded in quartz veins in the natural gold state. But these natural gold is in fine grained form, even if visible gold can be seen, it is mostly in flake form, and fine grinding is necessary to make the gold grains to achieve monolithic separation. After fine grinding, mercury plates are set at the discharge end of the ball mill to pre-recover the coarse-grained gold as well as the bright gold that is ground into flakes. Since the mercury plate only recovers the coarse gold, while some of the fine gold is lost in the tailings, flotation sweeping of the tailings from the mercury plate is also required to maximize the recovery.

Coarse-grained Dipping Quartz Veinstone Gold Ore

As shown above, this gold mine belongs to the rock gold ore with natural gold embedded in quartz veins in coarse-grained state, and the beneficiation method of this rock gold ore is very simple. Because of the large size of the natural gold and the specific gravity difference with the vein, most of the gold can be recovered by gravity separation, and the tailings can enter the amalgamation barrel to further recover the fine-grained gold.



If the natural gold and sulfide, especially the sulfide iron ore dense symbiosis, sulfide iron ore is the carrier of gold, such gold ore in the beneficiation process will usually be sulfide will be selected at the same time, in order to guarantee the recovery rate. Thionite and other sulfides in the ore is mostly coarse-grained state, it has a very obvious specific gravity difference with the vein, so this type of gold ore beneficiation is also very simple. We can first recover the sulfides by gravity beneficiation, and then deep processing of the sulfides (concentrate) to extract the gold. Usually these sulphides are subjected to calcination or cyanidation processes to extract gold.
