Bauxite flotation process plant. 1. The mined bauxite mixture is screened through a single-layer or multi-layer screen surface by a vibrating screen; 2. Preliminary crushing of the screened aluminum ore by the jaw crusher. 3. The spiral classifier classifies the ore powder ground by the ball mill again.

Bauxite. Bauxite is a kind of mineral which is often collectively formed by gibbsite, boehmite or diaspore. The Moh's hardness is 1-3. Bauxite can be widely used in many industries, among which the most important application is to be used to refine aluminum and to work as refractory and abrasive materials, and as raw materials for high alumina cement.

The jaw crusher reduces the size of large rocks by dropping them into a "V"-shaped mouth at the top of the crusher chamber. This is created between one fixed rigid jaw and a pivoting swing jaw set at acute angles to each other. Compression is created by forcing the rock against the stationary plate in the crushing chamber as shown in Fig. 13.9.

The size distribution of the milled bauxite therefore becomes an important parameter and can influence the bauxite usage factor. Monitoring, care and maintenance of: crusher gaps, ball charge management, grate hole and mill liner wear, screen and trommel wear, hydrocyclone wear will all contribute towards improved particle size control.

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. This often requires more complicated processes, such as the use of a high-intensity wet magnetic separator, with fine grinding of bauxite to liberate the iron minerals.

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%. The beneficiation step …
