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.
Spiral concentrators will tolerate minor feed variations without requiring adjustment.
