Tungsten Slag Treatment Method

The present invention discloses a tungsten slag processing methods.

The tungsten slag processing method comprising the steps of: dissolving the feeding step, the tungsten residue and 50 ~ 65 ℃, HCl 15% to 30% of the mixed solution, and a stabilizer is added tungsten, after the completion of the reaction, and filtered to give an acidic solution; and recovering tungsten steps, the use of weakly basic anion exchange resin of the acrylic acid solution in the tungsten, the end of the liquid to obtain I, analytical-exchange resin with sodium hydroxide solution to give tungstate, sodium tungstate recovered from the obtained sodium tungstate.

Technical solutions applied to the present invention, the use of low temperature atmospheric leaching solution of HCl tungsten slag, tungsten recovered directly next method in acidic conditions, the recovery process is simple and low cost.
