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.

For fine-grained manganese ore and multi-metal symbiotic manganese ore, flotation can be used. ... With the continuous increasing proportion of difficult-to-select low-grade manganese ores, it ...
