Extraction Characteristics of Alumina from Gujrat Bauxites

Abstract

ALUMINIUM has been termed the versatile metal of the 20th century since it finds applications right from the kitchen to the spaceship. The growing popularity of this metal has been attributed to its outstanding physical and chemical properties, viz. lightness, high strength of its alloys, high electrical and thermal conductivity, good workability and the most important of all-its resistance to corrosion. Aluminium and its alloys find extensive applications in road transport, railways and aviation due to their good strength for relatively low weight. Aluminium also finds applications in chemical & food processing plants. Owing to its good electrical conductivity it finds use in electrical industries . Its strength, brightness, durab-ility and capacity to take anodic coatings and colours are the most important properties for its use for archite-ctural purposes.
