Detailed explanation-1: -Bauxite is the most common ore of aluminium. Extraction of aluminium metal takes place in three main stages: mining of bauxite ore, refining the ore to recover alumina, and smelting alumina to produce aluminium.
Detailed explanation-2: -Bauxite is the best and only material for making aluminum metal. Bauxite is used in chemical industry, refractory brocks, abrasive, cement, steel, and petroleum.
Detailed explanation-3: -Aluminum is primarily sourced from the rock bauxite. Bauxite is composed of aluminum hydroxide minerals such as gibbsite, boehmite, and diaspore. Bauxite forms in areas of intense weathering of aluminum-containing rocks, such as igneous or metamorphic rocks that are rich in feldspar.
Detailed explanation-4: -Globally, bauxite is the primary source of aluminum (Al) ore and a major industry in many countries including China, Australia, and Brazil. As such, grading Al concentration is of paramount interest in the mining process as is the need to determine concentrations of penalty elements.
