Possibilities of Manufacture of Alumina by Serpek Process

Abstract

Aluminum is an element that was discovered in 1825 and its commercial history of it covers only 60 yrs, It is one of the principal metallic products of the electrochemical industry. The principal ore of aluminum, bauxite comprises the hydrated oxides of aluminum, Al203, H20 which is known as diaspore, and Al203,3H,02 which is known as gibsite, together with associated impurities such as the oxides of iron, silicon, and titanium. Bauxite is produced by the weathering and alteration of aluminium silicate rocks and is widely distributed around the world usually in tropical. and semi-tropical regions, where the weathering process have proceeded at an accelerated pace, The bauxite deposits in India are primarily in Bihar, Central Provinces, Central India, Bombay Presidency, Madras, and Kashmir. These deposits consist of gibsite and diaspore as well as a mixture of both in different proportions. Indian bauxites are of superior quality with low silica content (0,9 25%) and rich in titania (8-13%), Total production of bauxite during 1938 was 14, 768 tons.
