Предложенно техническое решение для сгущения пульпы в условиях крайне низких температур (–50 … –60 °С), основанное на применении гидроциклона и пластинчатого отстойника в закрытых помещениях. Исследования проведены на пульпе, полученной после измельчения урановой руды Эльконского месторождения до крупности –0,3 мм.
