| Abstract: | A commercial trial was conducted by introducing hard rock to substitute steel balls as media for vertical mills in Yinshan Mine. After this amelioration, the particle size composition for flotation pulp has been optimized as the size distribution was narrowed and the over-grinded portion was reduced. The recovery of copper flotation process was increased by 1.5 percentage point and the total recovery increased by 0.9 percentage point. Meanwhile, motor power dissipation and steel ball consumption were lowered. |
