The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide. The bauxite is the primary source of aluminum to make cement that used for construction. Aluminum is used for transport carrier, consumer durables, packaging, electrical, machinery equipment, refractory bricks, and abrasives.
Bauxite ore is a heterogeneous mixture of minerals that contains aluminum hydroxide, iron oxide, titanium dioxide, and other compounds. The following are the key characteristics of bauxite ore: 1.
Wet grinding of the bauxite ore in rod mills, ball mills, or semiautogenous grinding mills to produce fine slurry. Digestion of the slurry by caustic soda (NaOH) at strengths exceeding 170 g/L in vessels under pressure at temperatures ranging from 145 to 265°C depending on the type of bauxite being processed.
This laboratory study investigates selective grinding and beneficiation options for a Greek bauxite ore. First, a series of batch grinding tests were carried out in order to investigate the grinding behavior of the ore and the effect of the material filling volume (fc) on the distribution of aluminium- and iron-containing phases.
