Continuous Improvement Strategies in the Mining Industry. Lawrence Berthelet General Manager Mining and Metallurgy, SNC Saskatoon, Saskatchewan Canada
In many gold ore processing plants, achieving comminution targets is a challenge due to changing ore characteristics. As deep pit mining continues, the Work Index of ores increase and it reaches a time when the installed energy input becomes lower than that required for comminution.
