Selective Flotation of Calcite from Fluorite: A Novel Reagent Schedule
Abstract: Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available. In this study, a novel reagent schedule using ci...
متن کاملFlotation Separation of Scheelite from Fluorite Using Sodium Polyacrylate as Inhibitor
The depressing properties of sodium polyacrylate (PA-Na) for scheelite and fluorite were studied by micro-flotation tests, infrared spectroscopy (IR), zeta potentials, X-ray photoelectron spectroscopy (XPS), and density functional theory (DFT). The flotation results reveal that the selective depression effect of PA-Na is better than that of sodium silicate, and PA-Na can depress fluorite more e...
متن کاملSelective Separation of Fluorite, Barite and Calcite with Valonea Extract and Sodium Fluosilicate as Depressants
Fluorite, barite and calcite are important industry minerals. However, they often co-exist, presenting difficulty in selectively separating them due to their similar surface properties. In this study, valonea extract and sodium fluosilicate were used as depressants to selectively separate them by flotation, with sodium oleate as the collector. The single mineral flotation results showed that va...
متن کاملRate of Recovery from the Action of Fluorite Rays
This paper is a report of some experiments upon the rate of recovery of Paramecium caudatum from the cytolyfic action of fluorite rays. The organisms were exposed to the radiation emitted through the fluorite window of the hydrogen discharge tube described in previous communications. 1,* The intensity of the radiation was such that an exposure of 8 seconds caused cytolysis in 57 per cent of the...
متن کاملScheelite-type NaEr(MoO4)2
Explorations of the A(1+)-RE(3+)-Mo(6+)-O(2-) (A(1+) is an alkali metal cation, RE(3+) is a rare-earth metal cation) quaternary systems prepared by the high-temperature solution growth method led to the title structure, sodium erbium bis-(molyb-date), NaEr(MoO(4))(2). It is isostructural to the scheelite structure (CaWO(4)) and is composed of [MoO(4)](2-) tetra-hedra with symmetry and [(Na/Er)O...
