energy and size reduction in mineral processing

IDENTIFYING OPPORTUNITIES TO REDUCE THE

mineral processing companies are increasing energy efficiency to reduce costs in the current financial conditions. One of the major issues with EEOs is the lack of data available on energy use, and more importantly the energy use linked to production data, that identify energy reduction opportunities.
