grinding ore in mining

  • Mineral processingWikipedia

    Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution the size reduction of particles is done by three types of forces compression impact and attrition.
