Abstract
The natural resources of refractory raw materials are declining and at the same time the consumption rate is increasing, particularly in iron and steel industries. Any attempt to identify a new raw material source from the waste dumps could solve the national economy as well as environmental problems. In view of this, fly ash from thermal power plant has been identified for use in the ceramic/refractory industries after suitable beneficiation. For this wet high intensity magnetic separation studies carried out on typical fly ash sample indicate that the non-magnetic fraction (product) containing 24% Al2O3, 67% SiO2, 1.7% Fe2O3could be achieved with 63% recovery. This product is acceptable as a ceramic and refractory raw material after the necessary blending.
