Bauxite production line and process solutions

Bauxite production line and process solutions

I. Solution Overview

Bauxite beneficiation production line and process solution provides a combined process of "washing - classification - flotation - magnetic separation" for different types of bauxite (alumina trihydrate, soft alumina monohydrate, hard alumina monohydrate). Through the design of multi-stage sorting, the aluminum-silicon ratio can be increased by 2-5 times, and the Al₂O₃ content of the concentrate is ≥50%, which can meet the demands of industries such as electrolytic aluminum and refractory materials.

Second, differentiated bauxite ore dressing process

1. Bauxite beneficiation process of trihydrate alumina type

   • Core process: washing - classification - flotation

   • Process characteristics:

     • High-pressure water gun washing (removing 80% clay)

     • Spiral classifier classification (+0.5mm/-0.5mm)

     • Ore slime flotation (oleic acid trap)

2. High silica type bauxite ore dressing process

   • Core process: grinding-flotation desilication

   • Key technology:

     • Stage grinding (up to -0.074mm 85%)

     • Combined chemicals (oleic acid:tarr oil:motor oil=1:1:1)

     • Sodium hexametaphosphate as dispersant

3. High iron type bauxite beneficiation process

   • Core process: magnetic separation-flotation combination

   • Equipment configuration:

     • High gradient magnetic separator (1.0-1.5T iron removal)

     • Reverse flotation desiliconization (sulfonate trap)
