mine schedule. Sample types Three major sample types are typically chosen. Samples are selected for initial reagent deÞnition to achieve the desired mineral separation. Separation may be a simple bulk ßoat ( pyritic gold ores, some copper ore with negligible pyrite) or as is the case for polymetallic ores, a complex multistage sequential

Energy costs typically comprise one of the largest ongoing costs of mining operations, of which 70% is devoted to the comminution of the ore (Norgate and Jahanshahi, 2010). Furthermore, the most significant energy cost occurs in the grinding circuit of the Milling section, where up to 97% of the energy cost is incurred (Ballantyne et al., 2012).

Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Uranium, which may be colocated with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice.
