  • optimum particle size for copper ore processing

    In mineral processing, all ores will have an optimum particle size which maximizes the economic benefits from the net smelter return while minimizing the cost of crushing and grinding. If the particle size is too coarse there will be inadequate liberation, limiting recovery (and thus revenue) in the separation stage. Read More

  • Key Benefits of Particle Size Reduction: Part 2

    Sep 03, 2015· Improved Mineral Processing. Some forms of mineral processing, those involving ores, use comminution (particle size reduction) in order to improve the grade and recovery of the final product. This is a very delicate, finely detailed process, as particles that are too fine can prevent key concentration processes from happening.
