The indirect cost was estimated at 45% of direct capital costs and was considered to be within industry standards for the options considered. A similar approach was applied to estimate the total direct costs. It was found that both HPGR-ball mill and HPGR-stirred mill circuits have higher associated capital costs than the SABC option.

A comparative study was carried out for an alloy of Al 50 (Ni 75 Mo 25) 50 processed by two different high energy ball mills. A SPEX and Simoloyer mill were used.

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

The semi-autogenous grinding (SAG) mill is fed crushed ore at a nominal rate of 20,000 short tons per day (stpd) (18,150 tonnes per day) and is in closed circuit with a ball mill, two pebble crushers and two banks of cyclones, which produces a product for flotation.

Opportunities exist to eliminate equipment and reduce capital cost through various measures, such as the elimination of ball mills from the circuit, elimination of a pebble crusher and cyclone bank and optimization of the tailings preparation, resulting in less filtration. Environmental, Permitting and Community Impact

further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The mill operates in a closed circuit with screens that size the ore and cyclones that sort the ore by size and density.
