Analytical separations by means of controlled hydrolytic precipitationcobalt, nickel, manganese, titanium, etc., as well as copper and lead. In the separation of aluminum from chromium, neutralization to. pH 6.5 establishes the alkalinity most favorable to the minimum solubility of aluminum hydroxide. In platinum metal analysis, hydrolytic precipitation furnishes the only accurate means of.seperating platinum from cobalt and manganese,Separation of Cobalt and Zinc from Manganese, Magnesium, and .Aug 25, 2010 . The Boleo leach solution contains large amounts of manganese (45 g/L), magnesium (25 g/L) and small amounts of cobalt (0.2 g/L) and zinc (1 g/L) in sea water. Due to the high manganese concentration, it is very difficult to separate cobalt and zinc from manganese, magnesium, and calcium using.
