Bauxite Extraction Process — WORLDVEST PARTNERS

2019-2-20  Unlike the base metal ores, bauxite does not require complex processing because it’s usually mined at an acceptable grade. Ore quality can be improved relatively easily and cost-effectively by removing clay, known as “beneficiation” which includes washing, wet screening and mechanical or manual sorting.

Investigation into the question of complex processing

2013-5-8  A new technology of processing raw materials with the use of active alkali is suggested for bauxites of the Srednetimanskoe deposit; bauxite is opened at 300°C for 1 h. This technology makes it possible to increase the recovery of alumina to 94–98% and obtain red slimes and zeolite enriched with iron (58%) and titanium (4.8%); the environmental problem of storing red slimes is resolved.

Unlike its complex origins, the recycling of aluminum requires comparatively less processing; aluminum is broken down into shredded scrap, processed in a decoating kiln to remove any coatings or lacquers, and then melted and cast into ingots, ready for reuse. Conclusion. The journey from bauxite ore to aluminum is complex.
