    • Abstract
  • The grade of fine grain tungsten concentrates of Xingluokeng tungsten is greater than 55 %, but sulfur and arsenic are out of limits, the fine grain tungsten concentrates can not attain the standard of high quality, the WO3 lost badly in the sulphide ore moreover, because of that, the cost of production is very high. Therefore, the new technics of sulfur and arsenic reducing on fine grain tungsten concentrates of shaking table and fine grain tungsten concentrates of shaking table of middling after-grinding was used to substituted the quondam technics of sulfur and arsenic reducing on rough tungsten concentrate of shaking table and middling of after -grinding, the reagent regime also been optimized. The qualification of the content of S is less than 2.00 % and As is less than 0.20 % in the fine grain tungsten concentrates, WO3 losting is less than 1.00 % in the sulphide ore were achieved. The difficulty of production and management was solved; the new technics has a good economic effectiveness to the establishment.
