>Introduction to Mineral Processing or Beneficiation
Many older operations have rod mills in combination with ball mills. Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 1.5. As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed 2.5 cm.

Only by simple ball milling CaCO 3 was activated to release CO 3 2-to precipitate toxic Pb 2+ from nickel-containing solution.. Always over 99% Pb 2+ precipitated at a stoichiometric ratio of CaCO 3 in a wide range of nickel-containing wastewater.. Efficient Pb removal was also possible from other solutions of Cu, Mn, Ni, Cd, etc.
