Gold content in the ore is very low. To be able to extract gold, you’ll need do gold mine crushing and grinding and pre-enrichment by using dressing method or separate gold from the gold mine. There are numerous methods for gold dressing. Among these, gravity separation and flotation can be used more. Both methods?¡¥ difference is always that gravity separation plays a very important role in alluvial gold production while flotation is trusted beneficiation method in rock gold mine. Currently about 80% of rock gold mine in South Africa uses this process to choose gold.
Gold mine resources are mainly split up 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 incredibly rare and gold dressing is not easy. Now we has discovered 98 forms of gold ore and gold-bearing minerals , which only 47 species are typical, where there are just 10 forms of minerals which can be directly utilized in the industries.
The mainstream gold ore dressing technology is normally from the ore dressing equipment (crusher) to broken gold ore, then sent into the gold beneficiation (ball mill) being smashed and grinded. Following your gravity separation and flotation, concentrate ore and tailings are extracted, then through the use of chemical methods and final smelting, the finished product eventually be gold.
In the gold crushing process, raw ore will probably be delivered to vibrating screen after primary crushing. The most notable products will probably be crushed again and then blended with the middle products for together secondary crushing. The finished goods are then screened out. After screening, the last products will be sent into ball mill for grinding. There may be secondary grinding in accordance with products size.
For gold ore crushing, we usually choose jaw crusher for primary crushing and stand cone crusher for secondary crushing while short head cone crusher is utilized for fine crushing. To boost production and equipment utilization factor, Ore Dressing Plant generally follows the principle of more crushing with less grinding to lessen how big ore in to the grinding mill.
Because the leading mining equipment manufacturer, SBM can present you with the gold ore crushing equipment and grinding machine including vibrating screening equipment. Apart from jaw crusher, stand cone crusher, short head cone crusher and ball mill, SBM can also provide you with impact crusher, VSI crusher, mobile crusher, coal mill, Raymond mill, ruthless grinding equipment and coarse powder grinding mill.
If you’d like gold ore crusher or gold mine ball mill , SBM will probably be your most suitable choice.
