This book was released on 1969 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A continuous-flow contactor and ultraviolet spectrophotometry have been used to study the reaction between potassium ethyl xanthate, oxygen, and galena over periods of 20 to 30 hours. Quantitative results are presented for the reaction at a pH value of 10, but it is shown that the general features of the behaviour are the same within the range pH 8 to pH 11. Two types of reaction are observed. The first involves adsorption of the xanthate and takes place at a rate, dq/dt, that decreases exponentially with the quantity of reagent adsorbed: (dq/dt = a exp(-q/2.303 g)). The second is thought to involve reactions between the xanthate and the oxygen catalysed by the galena-xanthate surface. Its rate increases with time until it reaches a constant value, Rf. The period for which the adsorption reaction is dominant depends on pH. The presence of soluble reaction products in the reaction solutions was revealed by differential spectrophotometry. A tentative identification with the ethyl monothiocarbonate was made. When oxygen and xanthate are applied simultaneously to an unoxidized galena surface, an induction period is required before xanthate begins to react. The parameters of the adsorption-rate equation, and, therefore, the rate and extent of adsorption at any time, vary directly with the square root of partial pressure of oxygen (p) for p

Available in PDF, EPUB and Kindle. Book excerpt: Electronic Structure and Surfaces of Sulfide Minerals: Density Functional Theory and Applications examines the mineral structure and electronic properties of minerals and their relationship to mineral floatability by density functional theory (DFT). This pragmatic guide explores the role of minerals in flotation by focusing on the mineral surface structure, electronic properties, and the adsorption of flotation agents through the study of the microscopic mechanism of reagents from the structure and properties of minerals. The flotation mechanism is explained from the point-of-view of solid physics, which is of great significance for both theoretical research and practical applications. The study of the structure and properties of the minerals can reveal the essential nature of mineral flotation, hence why minerals have floatability, the mechanism of response of different minerals to different chemicals, and the origin of the selectivity of flotation agents. - Discusses the relationship between mineral properties and floatability in terms of crystal structure, atomic coordination structure and electronic properties - Covers the influence of the surface structure of the mineral on surface charge distribution, reactivity and electron density, including a quantitative calculation method for the atomic reactivity of the mineral surface - Includes research on the microstructure and mechanism of reagent molecules adsorption on the surface of minerals, focusing on the interactions between water molecules, oxygen molecules and reagents
