Use of polymer reagents for processing of potash ores containing clay slimes

摘要

Conditions have been established for use of polymer reagents in order to eliminate the negative effect of clay-carbonate minerals on potash ore flotation. It is shown that the flotation method provides more efficient desliming of potash ores than hydroclassification. The use of a combination of polyacrylamide polymers and surfactants for slime flotation provides the best efficiency. A new biodegradable reagent for slime flotation has been proposed. Requirements for depressants for potash ore flotation have been developed. A new depressant that actives sylvite flotation and improves slimes thickening and clarification of saline solutions has been developed.
