Method for Producing Ferrotungsten With Tungsten Carbide Obtained by Tungsten-containing Waste Processing as Raw Material

The present invention relates to a method for producing ferro-tungsten, tungsten-containing waste treatment especially to get raw materials for the production of tungsten carbide tungsten iron approach involves existing ferro-tungsten tungsten concentrate production process mainly as raw material, the use of an electric furnace as the main production equipment, production large, technology is more mature, but this process of smelting long time, high energy consumption, the complex process equipment operation, large area.

The present invention is to overcome the drawbacks of the prior art, the technical solutions adopted by the roasting is tungsten carbide, aluminum thermal reduction method and then through the production of tungsten alloy. Effective use of the present invention, tungsten-containing waste, to achieve a tungsten-containing waste processing, recycling, meaning significant resources; high recovery rate, significant economic benefits.
