摘要: In the mining process, linear, branched, hyperbranched or dendrimeric polyols or mixtures thereof are employed as process stabilization aids for aqueous solutions and, or suspensions of metal salts. A specific application area of the polyols is the stabilization of bauxite liquor in the Bayer process of producing alumina from bauxite.

摘要: Methods, and related products and compositions, of increasing the stability of a Bayer process liquor are described. A method of increasing the stability of a Bayer process liquor includes contacting the Bayer process liquor with a ppm quantity of a low molecular weight dextran. Also described are methods, and related products and compositions, for controlling the precipitation of aluminum-containing compounds from a Bayer process liquor.
摘要翻译: 描述了增加拜耳处理液的稳定性的方法及相关产品和组合物。 提高拜耳法溶液稳定性的方法包括使拜耳法处理液与ppm量的低分子量葡聚糖接触。 还描述了用于从拜耳法处理液中控制含铝化合物的沉淀的方法和相关产品和组合物。
