Hydrated potassium magnesium sulfate mineral material, notably schoenite and/or leonite, is heated sufficiently to drive off substantially all of its crystal water. The dehydrated mineral material is then held at a temperature above about 350* C. for a sufficient duration, usually at least 15 minutes, to substantially decreases the rate of moisture absorption from the

Dec 09, 2021 The operative “ideal” chemical reaction for this transformation is 2LiAlSi 2 O 6 + CO 2 → Li 2 CO 3 + Al 2 O 3 + 4SiO 2. When this reaction goes to completion, it can be shown that production of 1 tonne of lithium carbonate results in coproduction of 1.380 tonnes of alumina and 3.253 tonnes of silica, both potentially at commercial grades.
