Abstract

В заявке описан способ концентрирования водной суспензии твердых частиц, включающий стадии добавления по меньшей мере одного органического полимерного флоккулянта в суспензию, благодаря чему образуются флоккулированные твердые частицы, где флоккулированным твердым частицам предоставляют возможность образовывать слой твердых частиц и, следовательно, образовывать более концентрированную суспензию; добавления эффективного количества агента, который выбирают из группы, включающей свободнорадикальные агенты, окислители, ферменты и излучение, в котором агент вводят в суспензию перед или, по существу, одновременно с добавлением органического полимерного флоккулянта и/или органический полимерный флоккулянт добавляют в суспензию в сосуде и в суспензию в том же сосуде вводят агент. Этот способ особенно приемлем для разделения твердых частиц и жидкости, где флоккулированным твердым частицам позволяют выпадать в осадок седиментацией в гравитационном концентраторе.
