principles of ore grinding

  • 23.2 Principles of Extractive MetallurgyChemistry

    Sep 18 2019 · After mining large pieces of the ore feed are broken through crushing and/or grinding. This step creates particles that are either mostly valuable or mostly waste. TConcentrating the particles of value in a form supporting separation enables the desired metal to be removed from waste products.

    May 15 2014 · Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill where it then falls off the plates onto the rest of the ore charge.
