concentrate leaching for mica laboratory

  • Sulphide concentrate leaching

    The question as to whether concentration shall be included in the treatment of a given ore will often depend on the possibility or otherwise of recovering the precious metals from the concentrate at the mine. It may be suggested that if the concentrate can be cyanided after being separated from the gangue, why can it not be equally well cyanided if allowed to remain in the pulp going to the
