Electromagnetic Separation of Wolframite
The first magnet removes the strongly magnetic iron compounds and the second the wolframite, while the tin is contained in the nonmagnetic tailing. The tungsten concentrate and the tin product from the separator are both reconcentrated to eliminate waste. The raw ore yields 0.378 per cent. tin and 0.72 per cent. tungsten.
