The research aims to separate the Iron oxide from kaolinite by leaching the iron from the ore by using oxalic acid at different Quantities and at different (times, PH). The optimum conditions had been achieved was at morality 1.059 of acid the time was 2 hours &PH 3.2 the grade of iron in the ore was 5.72% and after the separation the iron in the concentrate becomes 1.25% so the percentage of removing Iron from kaolinite ore by this procedure becomes 78%.
