METHOD FOR THE MULTISTAGE, WASTE-FREE PROCESSING OF RED MUD TO RECOVER BASIC MATERIALS OF CHEMICAL INDUSTRY

摘要

The method of the invention is advantageously applicable to realize a multistage chemical process during which liquid clarifiers suitable for the purification of water and sewage, furthermore, fine-disperse pulverulent solid products utilizable as pait pigments and fillers may be recovered. Each final product of the multistage chemical processes is a useful material, so the whole technology is waste free.
