PHASES OF A MINING PROJECT Home | ELAW
grinding (or milling) the ore and separating the relatively small quantities of metal from the nonmetallic material of the ore in a process called 'beneficiation.' Milling is one of the most costly parts of beneficiation, and results in very fine particles that allow better extraction of the metal. However,
Chrome Ore Mining Process
smaller crushed chrome ore is fed to ball mill for grinding. Inside the ball mill, the crushed chrome ore will grind the ore to about mm with 3inch steel balls. 3. Screened products are transported to the jig for rough separation and to three concentrating tables for fine separation.

Coarse and Fine Particle Flotation Recovery
See Figure 2. This practice allows the advantages of coarse flotation to apply to the whole ore, followed by the advantages of fine flotation to its valuable part. At the same time the disadvantages of fine flotation are restricted to a small part of the bulk of the ore, with the marked advantage of lower costs due to coarse flotation.
