Определены оптимальные условия отмывки галита из полигалитовой руды (расход и температура воды, время контактирования твердой и жидкой фаз, степень измельчения руды), обеспечивающие получение чистого полигалита и фильтрата, близкого к насыщению по хлориду натрия при низких потерях полигалита.</p></abstract><trans-abstract xml:lang="en"><p>A study of treatment of polyhalite ore was conducted by the method of washing halite using water as a washing liquid. The optimal conditions for washing halite from polyhalite ore (water consumption and temperature, contact time of the solid and liquid phases, ore grinding degree) were determined, providing the production of pure polyhalite and filtrate close to saturation with sodium chloride at low polyhalite losses.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полигалитовая руда</kwd><kwd>галит</kwd><kwd>обогащение</kwd><kwd>извлечение</kwd><kwd>метод отмывки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyhalite ore</kwd><kwd>halite</kwd><kwd>treatment</kwd><kwd>extraction</kwd><kwd>washing method</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Баталин, Ю.
