How can we reduce operating costs with little or no capital?

Decades of conducting plant test work with the operators has provided Metcom the chance to identify a number of opportunities common to most ball milling circuits. Review the following list of questions to see how your operation might quickly benefit from one or more low cost, or no cost, methods to increase grinding circuit efficiency and reduce concentrate net production costs.

The following questions relate to the set up of the pumps and cyclones, specifically how well do they achieve maximization of the use of mill energy on coarse sized (versus already finished size) material? Please see our video on “Classification System Efficiency” (or “CSE”).

Minor adjustments to existing equipment (e.g., pump speed or cyclone orifice dimensions) sometimes can yield significant improvements in “CSE”. You can benchmark your own mill’s CSE value against what it should be achieving usingTable 5 in the reference paper in September, 2014, Mining Engineering.

Constraints in different plants will vary. However, you may find one or more of these suggestions provide a workable means to low cost, or no cost, grinding efficiency improvements at your facility, as they have done for other operations.
