flotation of a very low grade sedimentary phosphate

 

The Beneficiation Processes of Low Grade

2018 12 17&ensp·&enspThe enrichment of the low grade phosphate ore of ther Nefta deposit was investigated using scrubbing attrition, ball grinding and anionic/cationic reverse flotation in order to separate phosphate rich particles from their gangue. The choice of the beneficiation process was based on the petrographic, mineralogical and chemical analyses.
