for beneficiation of low grade manganese ore, containing siliceous matter as a major gangue material, by the froth flotation method. These authors have recommended the use of 05 lb. of oleic acid as collector for pyrolusite, 06 lb. of sodium silie as depressant for silica and lb. of eucalyptus oil as frother per ton of the ore. They have also observed that a pulp density of 30% solids ...
