Beneficiation of bauxite

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 ...

Jul 02, 2021  高达10%返现  Processing of bauxite for smelter grade alumina is quite sensitive to bauxite recovery and total cost for processing of ore, particularly in wet beneficiation. On the other hand, owing to homogeneous nature and consistent quality, some alumina refineries prefer washed ore compared to simple crushed run-of-mine (ROM) bauxite.

Mining and Refining – Process - World Aluminium

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting.

Beneficiation of fine Weipa bauxite tailing

Two types of Bauxite are mined in Weipa, Northern Queensland, and are designated as Andoom and Weipa ores depending on the deposit. To improve the grade of these ores washing is usually done which results in a lot of the constituent siliceous material being washed away. The resultant bauxite product then achieves a grade of about 60% Alumina with about 5% Silica.
