Abstract

1. Способ обогащения шламов, включающий сгущение шламов, их обогащение и обезвоживание продуктов разделения, отличающийся тем, что после сгущения из шламов в центробежном поле выделяют обезвоженный осадок и фугат, при этом обезвоженный осадок присаживают к концентрату, а фугат сгущают, обезвоживают и в зависимости от требуемой зольности товарных продуктов, например, не более 10%, направляют в присадку к промпродукту, полученному при обогащении угля, к необогащенному шламу или в отходы обогащения. ! 2. Способ по п.1, отличающийся тем, что разделение в центробежном поле проводят в фильтрующей шнековой центрифуге.1. A method of sludge enrichment, including sludge thickening, their enrichment and dehydration of separation products, characterized in that after thickening the sludge and centrate are separated from the sludge in a centrifugal field, while the dehydrated sludge is added to the concentrate, and the centrate is thickened, dehydrated and depending of the required ash content of marketable products, for example, not more than 10%, is sent to an additive to industrial product obtained by coal enrichment, to non-enriched sludge or to enrichment waste. ! 2. The method according to claim 1, characterized in that the separation in a centrifugal field is carried out in a filtering screw centrifuge.
