Bauxite Mines In Indiairon Ore Tailings

talk:bauxite tailings - wikipedia,answer: economics. probably the highest quality aluminum ore (bauxite) has been exhausted, so we are stuck with the fe-containing crud. low grade ores generate lots of waste. but industry increasingly turns toward lower grade ores. now maybe there are more benign reagents than koh/naoh to process the low grade ore so that the waste is not so corrosive..bauxite tailings. red mud waste - atarfil [2021 ] - atarfil,bauxite tailing liners bauxite is the naturally way form of aluminium ore, being the world's main source of aluminium. it is often strip mined/open-pits and normally processed into alumina. approximately four or five tonnes of bauxite are needed to produce one tonne of aluminium. over 95% of the alumina produced globally is through the bayer.
