Abstract

Изобретение относится к способу улучшения фильтруемости и результата промывки мелкозернистого отработанного материала, полученного в металлургической промышленности. В соответствии со способом в первый отработанный осадок перед фильтрацией добавляют некоторое количество другого мелкозернистого твердого вещества, которое также удаляют из процесса, и которое остается стабильным при таких же условиях, что и первый отработанный осадок.
