Aqueous chemistry of lithium production
Free white paper originally presented at the ALTA conference
This paper presents an overview of the aqueous chemistry found in lithium processing, in which both chloride and sulphate systems are used depending on the source or technical preference. The various simple and complex salts and their associated solubilities are examined via modelling of the relevant chemistry. Potassium being a by-product of interest, the equilibrium chemistry of potassium in chloride and sulphate solutions of sodium, potassium, magnesium and calcium is covered.
