Abstract
A solution of lithium sulphate is obtained by leaching the product obtained by mixing a lithium ore, at least 80% of which has a particle size of 44 microns or less, with at least 25% by weight of sulphuric acid of 25-100% by weight strength and heating # the mixture to 245-400 DEG C. at at least 50 p.s.i.g. Ores referred to are raw or decrepitated spodumene, amblygonite, lepidolite and petalite. In a modification water may be added to assist in supplying the acid to the powder evenly, provided the proportion of sulphuric acid in the total acid plus water is at least 25% by weight. Where the amount of water added is such that the pressure would increase above 500 p.s.i.g. during heating, the gases may be bled off, or in the initial heating the reaction vessel may be kept open until a temperature of 125 DEG C. is reached; such a temperature may be attained by the mixture without application of heat. Detailed examples are given.
