Modification of the Mineral Composition of Metallurgical Sludges during Gas-Phase Treatment in Nitriding Media. Part I. Fly Ash from the Concentration Plant of the Norilsk Mining and Metallurgical Combine
摘要
Abstract
Phase transformations in fly ash from the concentration plant of the Norilsk Mining and Metallurgical Combine were examined by X-ray microanalysis and X-ray diffraction phase analysis during gas-phase treatment in a HNO3 (vapor)–air atmosphere, followed by treatment of the resulting products with water.
