Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tungsten which means "heavy stone". Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone. It was identified as a new element in …
Description. Tungsten & High Intensity Wet Magnetic Separator. Wolframite minerals, being weakly magnetic with a specific susceptibility of 39×10 -6 to 46×10 -6 cm³/g, can be effective separated from cassiterite and other nonmagnetic minerals and gangue using a high-intensity wet magnetic …

The ore is first crushed and milled to liberate the tungsten mineral crystals. Scheelite ore can be concentrated by gravimetric methods, often combined with froth flotation, whilst wolframite ore can be concentrated by gravity (spirals, cones, tables), sometimes in combination with magnetic separation.
The tungsten grade is higher than the original ore, grade is 14% to 15%. Extract tungsten from slime is an important method for improving the tungsten recovery rate. Wolframite slime concentration machines have shaker tables, centrifugal concentrators, belt chute, flotation, magnetic separation.
Sep 29, 2019· The high-gradient magnetic separation was used to recover the wolframite from the scheelite flotation tailings. After one rough selection, one scavenging, and strong magnetic separation, it was found that the 0.43% f WO3 grade wolframite strong magnetic concentrate obtained from the 0.20% WO3 tailings, the tungsten …
