Bauxite Beneficiation: An Approach to Value Addition in
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.To explore the influence of thermal activation and particle size on cementitious activity of bauxite tailings, in this study, the raw bauxite tailings were classified into coarse bauxite tailings (CBT) and fine bauxite tailings (FBT) by a powder separator, and then the effect of activation temperature on cementitious activity of CBT and FBT was Effect of thermal activation and particle size on cementitious

Raw Bauxite by Artha Mineral Resources. Supplier from India
Supplier From India. Bauxite is a soft, whitish to reddish-brown rock consisting mainly of alumina-bearing hydroxides, oxides of iron, silicon and titanium with impurities of Ca, Mg, Cr, V, P, Ga and other elements. Raw Bauxite is a major source of aluminium. Basic alumina containing minerals of Bauxites are gibbsite Al (OH)3, Boehmite g-AlOThe utility model relates to a raw ore pulp production system of bauxite. A bauxite raw ore pulp grinding system is characterized in that a bauxite raw ore storage device is input and communicated with a mill feeding hole, a mill discharging hole is communicated with an intermediate tank, an intermediate tank outlet pipeline is CN213000524U Bauxite raw pulp grinding system Google

Comminution and classification technologies of iron ore
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.The invention discloses a pelletizing method for high-iron bauxite ore. The pelletizing method for the high-iron bauxite ore comprises the steps that the high-iron bauxite ore is subjected to fine grinding treatment so that high-iron bauxite ore powder can be obtained; the high-iron bauxite ore powder is added with sodium hydroxide, limestone and water and then Pelletizing method for high-iron bauxite ore Google Patents
