Bauxite production line processes alumina-rich bauxite ore for beneficiation and industrial use.
The main process includes washing, preliminary separation, calcination, crushing, grinding, classification, separation, concentration, and filtration.
Bauxite crushing commonly adopts a three-stage closed-circuit crushing process.
Grinding and classification usually use a grid-type ball mill and hydrocyclone closed-circuit system, with -0.074 mm above 90%.
Flotation commonly adopts one roughing, two cleaning, and two scavenging stages for bauxite separation.

The bauxite production line uses washing, crushing, grinding, classification, flotation, concentration, and filtration to improve bauxite concentrate quality.
Three-stage closed-circuit crushing, closed-circuit grinding, and optimized flotation help improve processing efficiency and reduce unnecessary energy consumption.
The production line can be configured with automatic feeding, washing, crushing, grinding, classification, flotation, concentration, filtration, and material conveying systems.
The process can be customized according to bauxite ore grade, particle size, grinding fineness, production capacity, and final concentrate requirements.
Bauxite ore is used as the main raw material for different production applications.
Bauxite ore is crushed to prepare suitable material size for further processing.
Crushed bauxite is screened to classify suitable particle sizes for different applications.
Screened bauxite is roasted to improve material quality and prepare high-alumina products.
Processed bauxite can produce alumina clinker with Al₂O₃ content ≥48%.
Alumina clinker is further crushed, screened, and roasted for refractory high-alumina materials.
Bauxite can be processed into brown corundum with Al₂O₃ content of 94.5%–97%.
Brown corundum is used for abrasives and abrasive material production.
Bauxite can be processed into alumina through Bayer process, sintering process, or combined process.
Alumina is converted by electrolysis into aluminum ingot for ships,
