The application has shown that the recovery of gold can be very high, as much as 99% and the concentration ratio is up to 1,000 times. In the recovery of natural gold in lode ore that has a particle size of -0.074mm, the gold recovered is about 98%, for recovery of gold in a particle size of 0.004mm, it is up to 97%.

Ball Mill is a type of ore milling machine used to grind materials into an extremely fine powder, mainly used in the mineral ore processing industry. Ball Mill could grind various ores and other materials either wet or dry, depending on requirements. It consists of a large cylinder which slowly rotates around a horizontal axis.

This work focuses on the characterization of heat generation during dry fracture by direct impact of a tantalum ore. Moreover, an attempt was made to quantify the heat energy loss to the environment during the grinding process of a ball mill. The study was carried out using mineral samples from a Spanish mine that were characterized by ...

Crushing & Grinding: The mined tantalum and niobium ore is first crushed by crushers and then sent to a ball mill to ground fine powder. Gravity separation: If raw ore contains niobite, cassiterite, zircon sand, ilmenite, tantalite and other valuable metals, the specific gravity difference is relatively large; usually use jig separators to ...
