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].

Dry beneficiation of Al2O3 25% to 55% is possible through various methods, including physical and thermal treatments. One possible approach is to use a method called "calcination," which involves heating the ore to high temperatures to drive off volatile components and promote the formation of higher-grade aluminum oxide.
