<p>In the process of separating sylvinite into its components potassium chloride from sodium chloride by froth flotation, in which potassium chloride is recovered in the tops and sodium chloride is left in the bottoms, the potassium chloride yield is increased, and its contamination with sodium chloride diminished, by the pressure of a sodium chloride crystal habit modifier in the flotation system. The modifier can be added to the flotation, or to the sylvinite, or even to carnallite before its decomposition into magnesium chloride and sylvinite.</p> |
