The test data show that, for comparable grinds and reagent dosages, the choice of grinding media has a marked effect on the paymetals recoveries and the selectivity. The ceramic mill produced the highest recoveries but the poorest selectivity. The steel mill produced the converse result. It is proposed that this is because the ceramic mill produces an oxidizing environment, allowing sphalerite ...
