Abstract
Phosphate ore requires processing to reduce the presence of gangue minerals like silicates, carbonates, and clays to meet the standards of phosphate industry. Enhancing phosphate beneficiation is essential to maximize resource utilization and support sustainable fertilizer production. This research explored the enhancement of Abu Tartur phosphate ore through beneficiation using several novel collectors including 2, 2-(Octadecyl azanediyl) di-ethanol, and 2-oxobutanol compared to oleic acid. Parameters affecting flotation, such as pH value, collector dose, and depressant dose, was studied. Also, measurements of zeta potential were conducted to follow up the interaction between the studied collectors and the phosphate sample. The results revealed that column flotation technology is a promising method for the beneficiation of Abu Tartur phosphate ore. Among the collectors tested, 2-(Octadecyl azanediyl) di-ethanol proved as the most effective, achieving a phosphate concentrate with 27.80% P2O5 with a high recovery rate of 88.50%, starting from a sample containing 20.60% P2O5. Also, under optimum flotation conditions using 2, 2-(Octadecyl azanediyl) di-ethanol, the total content of rare earth elements (REEs) was enriched to 1135.35 ppm.
