Abstract:Flocculation sedimentation test was carried out on the coal slurry of the selected coal preparation plant. A mathematical correlation model of initial settling velocity, upper clarification turbidity and sediment volume with various influencing factors was established. The results show that: the initial settling velocity increases first and then decreases with the increase of flocculant concentration; when the flocculant concentration is 10g/m3, the initial settling velocity is the largest; the initial settlin… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
