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.
