In gold mining

Gold content in the ore is very low. In order to extract gold, you need do gold mine crushing and grinding and pre-enrichment by using dressing method or separate gold from the gold mine. There are lots of methods for gold dressing. Among these,gravity separation and flotation is used more. The two methods’ difference is that gravity separation plays a very important role in alluvial gold production while flotation is widely used beneficiation method in rock gold mine. Currently about 80% of rock gold mine in China uses this method to select gold.

Gold mine resources are mainly divided into two categories: one for the vein gold mine, deposits mostly in the mountains, formed by the internal geological forces (mainly volcanism, magmatism, metamorphism), also known as rock gold mine or Endogenous gold; and the other for alluvial gold.

Gold resources are very rare and gold dressing is not easy. Now we has discovered 98 kinds of gold ore and gold-bearing minerals , of which only 47 species are common, and there are only 10 kinds of minerals which can be directly used in the industries.

Our European Type Jaw Crusher is an important stone crusher (rock crusher), which has been developed to crush high or medium hardness material, such as iron ore, copper ore, limestone, quartz, granite, and sand stones, ect., in metallurgical, construction, road building, chemical, silicate Industries.
