Abstract
Crushed caliche together with fines is leached at atmospheric or tepid temperatures, not higher than about 60 DEG C., so as to bring the available nitrate into complete solution. The enriched liquors mixed with stabilizing agents of the kind described in Specification 188,634, to avoid contamination of nitrate with sulphate crystals, are passed through heat exchangers, the temperature range being e.g. 25 DEG C. to 6 DEG C., and then subjected to agitation and further cooling, e.g. to 0 DEG C., in refrigerators to remove a portion of the nitrate content by crystallization. Mother-liquor returns to the leaching tanks through the heat interchangers, and through the ammonia condenser in cases where cooling is effected by ammonia vaporization. Impurities consisting mainly of sodium chloride and sodium sulphate remain in solution at the temperature of the heat interchangers from which nitrate crystals substantially free from sulphate are obtained. Further, with the production of solutions of high concentration in nitrate and in the presence of stabilizing agents, the concentration of sulphate is maintained low enough to permit of the crystallization of substantially pure nitrate during vaporization at or below 0 DEG C. The nitrate product is obtained in crystals of uniform size, has a potassium content of about 0.5 to 0.7 per cent and in general not exceeding 1 per cent, a perchlorate content not in excess of about 0.1 per cent and is relatively non-hygroscopic.
