Abstract

Предложен способ концентрирования суспензий твердых частиц в водной среде, включающий введение в суспензию как минимум одного органического полимерного хлопьеобразователя и добавление системы реагентов, при котором твердые частицы в суспензии образуют хлопья под действием как минимум одного органического полимерного хлопьеобразователя и образовавшиеся таким образом хлопья твердых частиц осаждаются с образованием осевшего слоя твердых частиц в водной среде, причем система реагентов включает i) как минимум один оксидирующий реагент, ii) как минимум один контрольный реагент.
