When the particle size of gold in the ore is 1 ~ 0.42mm, the recovery was 82%, and when the particle size is 0. 42 ~ 0.2 mm, the recovery rate is only 60. 5 %. There is a contradiction between the feeding concentration of the clay trough on the gold mining ship and the washing effect of the cylinder trommel screen.

The installed mill power limitation of 500kW gave a design specific grinding energy (SGE) of 7.84 kWh/t. The HIGmill size was a 500kW unit with a 4000L body (HIG500/4000, henceforth HIG500). This mill size has a small footprint of ~2.7m x ~2.3m. The small footprint made fitment into Cracow's existing plant possible.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Improving Gold Recovery Rat So it's a good idea if miners adopt the practice of using a jaw crusher and then a hammer mill or ball mill etc that will reduce the ore down to 100 passing 2mm or even 100 passing 1mm in size This latter size is perfect for running on a WTJun 11 32 These Mongolian ASM formed a hard rock quartz ore mining co op and ...

Not all refractory gold ores give a large recovery improvement after fine milling. Gold locked in arsenopyrite for example does not achieve the same gold recovery as gold disseminated in pyrite due to the smaller gold particle size of the locked gold (Figure 5). Figure 5.

SAG mills are used predominantly with feed material with a larger max lump sizes (from primary crushing plant typically in the max lump size range 150 mm to 300mm and a psd to follow) and the ball or rod mills are for smaller feed lump sizes. The final product size depends on the retention time and grinding capability of the type of mill.

Gold ore ball mill can grind the gold ore in dry-type or wet-type, and it is widely used by large scale metallurgy, pure gold ore and gold ore recovery enterprises.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
