For typical lateritic ores worldwide, the core aluminum-bearing mineral is boehmite, which often coexists with iron-bearing minerals such as hematite and goethite in a fine-grained dispersed or cemented state. In such symbiotic relationships, iron oxides are mostly in the form of matrix filling the interstices of bauxite or coating the aluminum minerals, making the "iron removal and aluminum preservation" in some ore sections quite challenging. Therefore, in actual production, it is necessary to optimize based on the particle size dissociation characteristics and process separation methods.
 

Bauxite of the gibbsite type is prone to generating fine particles during crushing and grinding. These fine particles not only reduce the degree of monomer dissociation but also cause the mineral surface properties to become similar, leading to non-selective adsorption of reagents and foam entrapment, which results in a decrease in the recovery rate of alumina. In response to the "fine particle dilemma", some studies have proposed selective flocculation as a supplementary approach: using high-molecular flocculants such as polyacrylamide to selectively flocculate and settle gibbsite, while kaolinite remains suspended, thereby achieving the separation and enrichment of fine particles. The optimal pH range is 9 to 10. Flocculation flotation involves using flocculants to aggregate fine particles into larger flocs, which then exhibit the characteristics of conventional-sized minerals. After being hydrophobized by collectors, they are carried up by bubbles, achieving separation from dispersed gangue.Bauxite of the gibbsite type is prone to generating fine particles during crushing and grinding.
