Flotation Production Practice in Low-grade of Carbonic-acid Manganese Ore

This paper tells of the industrialization practice pilot of run success in Hunan province,dealing with low grade of carbonic acid manganese ore in the new flotation machine technology and a new application of technology of collector.And it makes the low grade carbonic acid manganese ore with manganese 7%～10% win no less than 17% in carbonic acid manganese ore concentrate,with manganese recovery rate of more than 85%.
