Résumé:
Phosphate rock needs processing to reduce the content of gangue minerals such as carbonates, quartz
to meet the requirements of the phosphate industry. In this paper the relationship between the
flotation performance of the phosphate ore collectors and their adsorption behavior was evaluated
using analytical techniques and more advanced techniques. The adsorption of the collectors on the
surfaces calcite, dolomite, phosphate and quartz was evaluated via zeta potential, FTIR,
spectrophotometry and microscopy analyses. The flotation performance of the collectors was
evaluated using laboratory mechanical flotation cell at different process parameters such as pH,
collector dosage
