Recycling of Fly Ash and Industrial Waste as Sinter ore During Metallurgy Process

Abstract

Fly ash is classified as a hazardous waste. So it should be specially treated. Industrial waste from Iron and Steel Co. containing blast furnace dust, converter dust, pyrite cinder and mill scale etc., should also be treated before disposal. However, specific research on both fly ash and industrial waste in a work was rarely reported. In this paper, sinter ore was made from fly ash with the addition of industrial waste by metallurgy process. The results showed the produced sinter ore met strength and metallurgical properties standard. And the leaching concentration of sinter ore was lower than the Chinese regulatory thresholds.
