crushing an ore as finely as possible to seperate minerals from gangue

  • Ore Dressing

    The jigs, tables and flotation each make clean concentrates to be saved and waste tailings to be discarded and usually also a middling product which, if coarse, must be recrushed and retreated or, if fine, needs only retreatment with out any crushing If the sulphides are finely disseminated through the gangue, the ore is crushed down to mm or.
