'Method for Increasing Stability in Process Salt Solutions of Mining Systems, Method for Improving Aluminate Stability in a Turgid Bayer Liquor, and Method for Increasing Aluminate Stability in the Bayer Red Mud Circuit'

摘要

A hyperbranched polyglycerol is employed as a process stabilization aid of pregnant liquor of a Bayer process of producing alumina from bauxite. The hyperbranched polyglycerol has a molecular weight of from about 1,000 to about 1,000,000.
