Bauxite is a primary aluminum ore often with a pisolitic structure. The sample is collected from Bagru Hill/Group of openpit mines, operating since 1933, Jharkhand, India. The principal uses of bauxite are multipurpose covering metallurgy, chemical industries, as raw material in building and road aggregates.

The silica present in the bauxite tends to be concentrated in the finer grained fractions, and this characteristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of % silica, the minus 100 mesh fraction analysed a silica .
In 2015, the US Geological Survey estimated that over 95% of bauxite was converted to alumina, with the remainder going toward a variety of products such as abrasives, chemicals, proppants, and more. The primary approach to transforming bauxite ore to alumina is known as the Bayer Process.

· Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilie, and other impurities in minor or trace amounts. Bauxite deposits are formed by the decomposition of a wide variety of rocks rich in aluminium silies.
The mining lease is approximately 7,000 square kilometres and provides access to bauxite to 2044. Willowdale produces bauxite that is supplied to AWAC's Wagerup alumina refinery in Western Australia. The mining leases provide access to bauxite to 2044. The annual mining rate of Willowdale is approximately 10 million metric tonnes of bauxite.
At Noranda Bauxite, we mine and ship highquality bauxite with lowcost processing characteristics. Our bauxite has a silica content of less than 2% and a small particle size. This means the process for crushing and grinding is not as intensive. The small particle size and low silica content make our Bauxite one of the highest in value worldwide.
during mining as both top bottom profile of bauxite are highly undulating in nature. So every 1% excess of results more consumption of caustic soda and creates digestion problem. • Hence, threshold value of Silica in bauxite ore should be based on T. Silica content (<5%), rather than which can also be controlled during mining.
Bauxite Reserves. The top 5 countries, Guinea, Australia, Brazil, Vietnam and Jamaica, hold over 70% of the world's documented bauxite reserves. Bauxite resources are estimated to be 55 billion to 75 billion tons, in Africa (32%), Oceania (23%), South America and .

The combination of good quality bauxite (about 4142 % Available alumina and ; % Reactive silica) and proximity to large river, not far away from main sea makes this deposit ideal for bauxite mining, value addition and export.
Beyler's bauxite is used as a high alumina source to adjust the feed for clinker production when the alumina content of the clay or shale feedstock is too low for the formation of the required alumina phases during sintering of the clinker. Main advantages of using Beyler's bauxite are the high Fe2O3, low silica, alkali and MgO content.
· Metro Mining Ltd hopes to mine up to 2m tpa from its Queensland Bauxite Hills project, which contains a tonne high grade reserve (% alumina and % reactive silica (SiO 2)).

· Abstract. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, in the form of kaolinitic clay, and also to increase the alumina content. Additionally, reduction in iron content, particularly in the form of goethite, and reduction of organic carbon can also increase the value of the bauxite product.
Bauxite mining and processing is known to have a large environmental impact due to extensive production of toxic waste, ... Silica forms a residue in the leaching process and is extracted as a byproduct. Aluminum is extracted through a sparging process and subsequently calcined to form alumina.
