HYDROMETALLURGICAL PROCESSING OF EGYPTIAN BAUXITE

Hydrometallurgical Processing of Egyptian Bauxite 433 Fig. 1. Sketch of the attritor Technique of Work Gibbsite and kaolinite were separated from detrital quartz by first pulverizing in a ball mill and then screening through a 63 micron screen. The fines were repulped in water, dispersed thoroughly and then allowed to settle.

Hydrometallurgy - Wikipedia

Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy. …
