Аннотация

This article analyzes the processing stages of scheelite concentrates, including acid decomposition, roasting (sintering), and selective leaching. It is shown that direct precipitation of tungstic acid during hydrochloric acid decomposition simplifies the technological process. Roasting with soda and nitrate at 800–900 °C ensures the conversion of tungsten into sodium tungstate with an extraction rate of 98–99 %. Selective leaching at 80–90 °C allows nearly complete transfer of tungsten into the solution. The obtained results demonstrate that the proposed technological scheme is an efficient, cost-effective, and environmentally sound method for processing tungsten concentrates.
