Mahmut MAT. -. Modified date: 23/04/2023. Tungsten, abbreviated as W on the periodic table, is a rare and valuable metal known for its exceptional physical and chemical properties. Tungsten ore refers to the natural rock or mineral containing tungsten in its compound form. Tungsten is commonly found in nature in the form of tungstates, The Challenge of Tungsten Skarn Processing by Froth Flotation: A Review. The greenest, most efficient, and cheapest method for scheelite flotation is to use fatty acids as collectors with sodium silicate as depressant, although this solution suffers from a crucial lack of selectivity regarding the above-mentioned calcium salts.[PDF] The Challenge of Tungsten Skarn Processing by Froth Flotation
