Abstract

Integrated studies of ion exchange extraction of tungsten was carried out in application to the carbonate solutions of autoclave leaching of raw material with low tungsten content. Anionite and desorbent for tungsten extraction were chosen. The integrated technology of processing tungsten-containing raw material was proposed, resulting in obtaining metal tungsten, with the possibility of regeneration of the treating reagent sodium carbonate.
