HIGHLIGHTS ON THE BENEFICIATION TRIALS OF THE EGYPTIAN PHOSPHATE …
introduction : Phosphate rocks are vital non-renewable resources and are essential components in agricultural fertilizers and phosphorous-based chemicals [1-4]. About 95% of the phosphate produced around the world is consumed in fertilizer industry [5, 6]. Phosphate deposits can be divided into three groups (і) sea sediments, (іі) igneous and (ііі) biogenetic deposits [7].
