Bauxite, also known as bauxite or bauxite, is a chemical or biochemical rock rich in aluminum minerals. It is mainly formed by strong thermal chemical weathering of aluminosilicate minerals, bringing out the dissolved alumina, which is transported to the sea-lake basin and deposited. Bauxite is an ore with a Mohs hardness between 1 and 3.

Bauxite is a low-level naturally occurring radioactive material. It contains small quantities of uranium (238U), thorium (232Th), and potassium (40K).7The low-level natural radioactivity present in the ore transfers almost entirely to the solid residue stream during refining—some to sand residue but most to mud residue.
The results showed that grinding of the ore exhibits non-first order behavior, while the breakage rate varies with grinding time. Additionally, Al 2 O 3 tends to concentrate in the coarser than 0.300 mm product fraction, while fc 10% and 2 min of grinding time are considered optimum conditions for good distribution of Al 2 O 3 and Fe 2 O 3.

12%Bauxite is a rock type that is used to produce metallurgical-grade alumina and chemical-grade alumina/aluminum hydroxide using the Bayer process [ 8 ]. During this process, the finely ground bauxite ore is digested under pressure in a strong caustic (sodium hydroxide) solution at temperatures ranging from 100 to 260 °C.
K is the grinding rate constant, t is the grinding time and M is a constant depending on the material properties and grinding conditions. The present laboratory study aims to investigate selective grinding and various beneficiation options for a Greek bauxite ore. First, selective grinding was carried out, through a series of batch
Conditions within the digester (caustic concentration, temperature and pressure) are set according to the properties of the bauxite ore. Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C.
