Procédé de séparation électrostatique de minerais potassiques

摘要

For recovering an enriched KCl fraction from potash ores by electrostatic separation, the ore is conditioned with a reagent comprising an aliphatic amine of 8 - 22 carbon atoms and an ammonium salt of a lower aliphatic carboxylic acid, e.g., laurylamine and ammonium acetate.
