    Complete stepbystep answer:The following three steps of the Bayer’s Process for the leaching or extraction of pure alumina from bauxite are as follows:(1) The bauxite ore, most important ore of aluminium, composed of silica, iron, and titanium dioxide as impuritiesOther major steps in the process are the precipitation of aluminum hydroxide from the sodium aluminate liquor and the calcination of the aluminum hydroxide to produce aluminum oxide (alumina) In this study the minus 15″ bauxite ore is groundExtraction Process of Aluminium from Bauxite OreAns: Following steps are involved in the extraction of Aluminium from bauxite 1The concentration of the ore through Bayer’s process (Leaching) In this process, bauxite is treated with N a O H to form sodium aluminate, which further reduces with C O 2Extraction of Aluminium From Bauxite, Bayer's & Hall's
