Purification Of Nigerian Antang Corundum For Advanced Ceramic Production
1115-9782 © 2018 Ife Journal of Technology
The study deals with purification of Antang corundum from Zanga LGA, Kaduna State of Nigeria for ceramic production. The experimental work was on the laboratory-scale beneficiation of Antang corundum for possible alumina production in advanced ceramic development. Froth floatation procedure was employed in beneficiating the corundum to get a high-grade alumina while depressing the other minerals by using laboratory-floatation equipment. The results from the experiments presented more than 32 % improvement in the alumina content of the corundum. The alumina content achieved was 86.6 %, which makes the corundum surpasses the 85 % alumina grade in the CoorsTek ceramic properties standard, commonly used for armour ceramic production. The Antang corundum can then be used as a substitute for bauxite and alum that are the major sources of alumina through Bayer process and calcination method respectively.
