Separation Of Feldspar And Other Minerals By Flotation Methods

Dec 01, 2018 Flotation is the only technique that enables the selective separation of Na and K feldspar minerals from each other. In this study, the flotation separation of Na-feldspar (albite) and K-feldspar (microcline) minerals were investigated in the presence of K + ion as counter ion. In order to identify the role of K + ions on the selective separation of feldspar minerals, solubility, adsorption

    The present invention provides a process for the separation of minerals by flotation in the presence of activators and suppressors. Activators are cation-active condensation products and suppressors are anion-active products of aminoplast formers, formaldehyde and amines, ammonium salts, acids or a sulphite, in combination with either an anion-active or cation-active tensides

    For the removal of coloring minerals from feldspar ore the most widely used method is reverse flotation method. Reverse flotation process is generally carried out in conventional mechanical cells. In this study, it was aimed to enrich low-grade feldspar by using cyclojet flotation cell which was developed as an alternative to conventional cell

This causes unsuccesful selective separation and also excessive reagent consumption [19,27,30–32]. For these reasons, removal of slimes for feldspar ore flotation is a necessity prior to mica and heavy mineral separation [10,13,16,19,33–39]
