The flotation tests were performed in a 40 mL FGC-type hanging tank flotation machine at an impeller speed of 1630 r/min. First, 2.0 g of the mineral sample was weighed into the 40 mL flotation tank, 36 mL of deionized water was added, and the pulp was stirred for 1 min to ensure it was as uniform as possible.

Five Kinds Technology Of Manganese Ore Beneficiation
Manganese flotation is a method of separating manganese minerals from other minerals by air bubbles. This method is usually used for fine-grained ores. During this process, a blowing agent is added to create air bubbles, which selectively attach to specific mineral surfaces according to their hydrophobicity or hydrophilicity.
