摘要： The present invention is a method of producing substantially dry water insoluble polymers from poly alkyl esters of vinylic monomers for use in a method for the clarification of red mud-containing liquors generated in the Bayer process for the recovery of alumina from bauxite ore. The polymers can be either homopolymers, copolymers or terpolymers. Preferably, the dried emulsion polymers are high molecular weight polymers of poly(methyl acrylate), poly(methyl acrylate/acrylic acid), poly(vinyl acetate/acrylic acid/methyl acrylate), poly(t-butyl methacrylate/acrylic acid/methyl acrylate) and poly(t-butyl acrylate/acrylic acid/methyl acrylate).

摘要： The invention provides a method of inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more particular silane based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.
