Current key options for management of industrial alkaline waste of alumina production (red mud)

Due to the ever-increasing demand of world economy for aluminum, its alloys and compounds, production this metal is increasing annually throughout world. This leads an increase in industrial alumina, which obtained from bauxite ore Bayer process. After recovering bulk aluminum ore, there remains a residue highly alkaline toxic waste, also called residues (tailings) or red mud (RM). About 140-150 million tons RM are produced almost 4 billion have already been accumulated. At moment, problem recycling development effective cost-effective approaches their reprocessing extremely urgent. Reducing affects economic, environmental, social areas prerequisite sustainable nature society. Despite active scientific research efforts develop optimize various methods reprocessing, annual volumes around unresolved. Recently, promising efficient processes proposed that allows complex with extraction number valuable liquid products may be fields industry. focus on large-scale disposal can solution handling these wastes. The article considers main current trends field management types zero waste concepts.
