Ball mills have been used for fine grinding for many decades. However, the main reason ball mills are not suitable for fine grinding is the perceived poor energy efficiency generally experienced when grinding to fine sizes. ... In addition, argentite and silver bearing gold minerals were also carrier minerals of silver in the ore, with contents ...

Calcination Roasting Process. The usual method of process and treatment of the calcines (by calcination) from the roasting of gold ores is to cool in air, quench the moderately cooled material in water, and subject it to a light grind with pebbles or balls to break up agglomerated particles, sintered prills, etc.

Conditioned pulp is pumped to the Argentite (silver mineral) flotation circuit. The three stage flotation circuit will recover floatable silver minerals remaining in the primary leach residue. Two banks of 4100 cu. ft. rougher flotation cells must recover as much of the silver mineral as possible within the 30 minutes allotted contact time.

Using this system, MSC enhances efficiency of the mill by maintaining the optimization parameters at all times. This is translated into a power reduction of 10 to 15% in similar mills. This technology is applied in the ball mills as well, further reducing power consumption in a conservative way by an additional 15%.
