Tailings may also contain chemicals used for mineral extraction. Tailings are distinct from "waste rock", which is the nonore rock which miners move and discard as they dig down to access the underlying ore.
Bauxite ore is the world's primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal.
Alternatively the Pretreatment of aluminium containing material nonmetallic components were separated by 90go, however, 3~ of the original aluminium con tent is lost therein. Subsequently 95~ of the foreign metals were separated, however, also in this step another 2~ of the original aluminium content is lost with the separated met als.
In this article, a new process, roasting with addition of soda followed by leaching, is developed to remove aluminium from the ore. Results show that Al 2 O 3 content decreases from % in raw ore to % in iron concentrate, and total iron grade increases from to % when the ore is roasted at 1000°C for 15 min with the addition of % (wt.) sodium carbonate.
This process uses starch (depressant) and amine (quartz collector) as reagents to promote the separation of the contaminant mineral (quartz) from the ironbearing mineral. The floated material from the flotation process is also sent to the tailings thickener.

The aluminiumcontaining bauxite ores gibbsite, böhmite and diaspore are the basic raw material for primary aluminium production. Proven, economically viable reserves of bauxite are sufficient to supply at least another 100 years at current demand.
Saves valuable finite natural mineral resources, only a finite quantity of metal ores, conserves a valuable mineral reserve mineral sources cannot last forever! Saves energy, so less fossil fuels burned, good 'green' economics. Its cheaper to recycle metals that to .
