RECOVERY OF ALUMINA TRIHYDRATE DURING THE BAYER PROCESS USING SCLEROGLUCAN |
摘要 |
The invention provides methods and compositions for improving the production of alumina. The invention involves adding a product containing one or more polysaccharides to liquor within the fluid circuit of the production process, where one of the polysaccharides is scleroglucan. The use of scleroglucan can impart a number of advantages including at least some of: greater flocculation effectiveness, increasing the maximum effective dosage, faster settling rate. The production process can be a Bayer process. |
