Abstract
In separating ammonium chloride from its mixtures with alkali metal salts, e.g. nitrates, sulphates, &c. by flotation, the flotation is effected in an alkaline medium and the froth recovered after flotation is destroyed by the addition of one or more acids, whereby pure crystals of ammonium chloride are obtained. The liquor obtained after the separation of the ammonium chloride may be treated to restore its alkalinity for re-use in a subsequent cycle of operations. After the removal of the froth, one or more bases may be added to the alkaline liquor before the separation of the alkali metal salts. After the separation of the alkali metal salts, the liquor containing the added bases may be treated to restore it to its original composition. The above described addition of acids and bases may be so determined that on combining the liquors remaining after the separation of the ammonium chloride and the alkali metal salts respectively, a liquor having the composition of the original alkaline flotation liquor results. The flotation may be effected at 20 DEG C., using flotation reagents such as sodium oleate, oleic acid, pine oil and cresol alone or in admixture, or a mixture of petroleum spirit and colza oil. Examples relate to the separation of ammonium chloride and potassium nitrate obtained by the reaction of potassium chloride and ammonium nitrate, and to the separation of ammonium chloride and neutral sodium sulphate.
