摘要

Procedure for the separation by flotation of sodium chloride from the cainite for the enrichment of the mineral cainite with the purpose of obtaining on the one hand the impurity of sodium chloride and on the other a residue formed by cainite, characterized because it is operated with the help of flotation and because the solution forms the pulp constituted by raw material crushed dry or wet in a solution suitably buffered by magnesium chloride is conditioned by a salt of lead and a cathodic reagent and carried the flotation by small successive additions of an alcohol that has the function of forming foam while maintaining as floated the sodium chloride while the flotation residue is formed by the practically pure cainite.
