Manganese (Mn) Ore Minerals, Occurrence,
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silvery-gray metal that is commonly found in the Earth's crust. Manganese is an essential trace element that The results of flotation tests showed that LHA possesses an excellent selectivity for the flotation of manganese ore, and the selectivity of LHA is better than that of the traditional collector OA. The flotation experiments indicated the concentrate of 97% recovery and 18.3% Mn grade were achieved at. AcknowledgementThe flotation of low-grade manganese ore using a novel
