Bastnaesite, Barite, and Calcite Flotation Behaviors with MDPI

The flotation of bastnaesite, as a major mineral source of rare earth elements, attracting much attention in the mineral processing field, is challenging owing to the natural flotability of calciumbearing minerals To promote the application of flotation, we systematically investigated the flotation behavior of bastnaesite, barite, and calcite, with Microflotation experiments indicated that the flotation recovery of fluorite is 8872% after fluoride ion treatment, that is, approximately fourfold with respect to that without fluoride ion(PDF) Effect of Fluoride Ion on the Separation of Fluorite from Calcite

Adsorption of a novel reagent scheme on scheelite and calcite

Section snippets Experimental minerals and reagents Pure scheelite was collected in Sichuan, China, and calcite was collected in Fujian, China Samples were broken into fine particles and screened to obtain a fraction of −74 + 37 μm for flotation tests and XPS analysisXray powder diffraction spectra of the two minerals (shown in Fig 1a As a common depressant, acidified water glass (AWG) has strong inhibitory effects on fluorite and calcite The inhibited fluorite is difficult to be recovered, thus resulting in the waste of resources and low flotation efficiency In this study, the interaction of fluoride ions with fluorite and calcite surfaces was investigated, and its effects of AWG Effect of Fluoride Ion on the Separation of Fluorite from Calcite

Recent process developments in beneficiation and metallurgy of

Abstract Rare earth elements (REEs) are irreplaceable materials supporting lowcarbon technology and equipment, and their commercial demand and strategic position are becoming increasingly prominent With the continuous depletion of rare earth (RE) resources, developing highefficiency beneficiation and ecofriendly Wollastonite and calcite minerals are significant raw materials and are extensively used due to their unique properties Wollastonite is used in plastics, paint, ceramics, paper, resins, and in construction as a substitution for asbestos due to its chemical stability, thermal resistivity, needlelike shape, and brightness Calcite is one of Physicochemical Characterization of Natural Wollastonite and Calcite

Selective Separation of Fluorite, Barite and Calcite with Valonea

Fluorite, barite and calcite are important industry minerals However, they often coexist, 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 The surface interactions and adsorption mechanism of alkyl hydroxamic acid bearing collectors and sodium silicate depressant on common carbonatite gangue minerals, including calcite, dolomite and ankerite in flotation were investigatedFor this purpose, firstly the flotation behaviors of these minerals in the presence of the collector Surface interactions and flotation behavior of calcite, dolomite
