Abstract:Potassium ore contains readily sludgable water-insoluble silicate–carbonate impurities which actively adsorb cation collectors (primary alkylamines) used in sylvine flotation. This fact determines inclusion of multistage de-sludging flowsheets, with rougher and cleaning flotation of sludge in the processing technology. A prerequisite for flotation de-sludging of ore is pre-flocculation of sludge. Flotation of sludge in mechanical flotation machines is carried out with intensive mechanical stirring of the suspe… 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.
