What is a ball mill used for in gold mining? LinkedIn
A ball mill is a grinding machine used to grind, blend, and sometimes for mixing materials for use in the process of extracting gold from ores in gold mining A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls. An internal cascading effect reduces the Ball mill

Optimal-Setting for Ore and Water Feeding in Grinding Process
The coarse ore from the primary crusher is mixed in the ore bin and then fed into the ball mill together with water for wet grinding. By changing the frequency of the pendulum feeder, we can control the quantity entering the ball mill. The tumbling and crushing action with the grinding medium grinds the coarse ore to finer sizes.Introduction. As coarse grained, easily processed ore bodies are depleted, more disseminated, fine-grained ores are being treated. Adequate liberation of valuable components within a fine-grained ore is often only achieved once the particle size of the ore has been reduced to levels below the traditional ball mill cut-off of 45. μm..

Ball vs Rod vs Roll Mills Gold Refining & Metal Extraction Forum
In the order you have listed; a ball mill can fine grind down to <400 mesh if needed, a rod mill will efficiently grind to 150/200 mesh range, and a roll mill can do a +/- 100 mesh. The ball and rod mills are similar in appearence, as a large rotating lined cylindrical tube filled with either metal balls or long rods used as the grinding medium.We sent a substantial amount of quartz gold ore to a mill for processing. After a couple hundred tests on the material an average grade was calculated. After milling for several days the mill says there is way less gold in the ore than what had been estimated.

It seems certain, however, that the ball-mill will crush to 200 mesh a considerably greater tonnage when the proper classification is provided. Since in previous tests the mill has crushed 7½ T. per hr. from ¼ in. to 200 mesh, it seems possible that it will crush at least 8 T. per hr. from 48 to 200 mesh.In general, only the dissociation of the sulfide ore monomer is required for gold encapsulated in sulfide minerals.
