| Abstract: | The comprehensive technology of recovering niobium-tantalum-tungsten was introduced by staged grinding,staged beneficiation,gravity separation of coarse particles and floatation of fine particles.The combination of new efficient chelating collector benzohydroxamic acid and assistant collector FW was applied in the floatation of niobium-tantalum-tungsten slime.Flotation concentrate was treated with micro-fine-shaking table.The recovery rate of niobium-tantalum-tungsten increased significantly out of a raw or... |
