USING POLYOLS AS REACTANTS FOR CONTROLLING DEPOSIT FORMATION IN MINING PRODUCTION METHODS Russian patent published in 2013 - IPC C01F7/06 C01F1/00 C01F7/34 C01F7/47 C07C41/46 C08K3/22 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of producing process salt solutions for mining production, particularly to increasing stability of said solutions. The method involves adding to the solution one or more linear, branched, hyperbranched or dendrimeric polyols or mixtures thereof as stabilising process additives. The process salt solution is a mother solution from a Bayer method, which is used in producing aluminium oxide from bauxite.

EFFECT: high stability of the aluminate in the mother solution and in red mud pipeline of a Bayer method.
