Beneficiation of bauxite [email protected]

2011-8-11  The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica, the minus 100 mesh fraction analysed a silica content as high as 10.30%.

Bauxite Beneficiation: An Approach to Value Addition in

2021-7-2  Non-metallurgical bauxite ore is generally sold at higher prices, and consequently can offset lower recovery and higher beneficiation costs. The primary objective of beneficiation for non-metallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values.
