Flotation Separation of Scheelite from Fluorite Using

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 effectively than scheelite. The flotation recovery of scheelite and fluorite keeps at about 75% and 10%, respectively, at the pulp pH 9.3~9.6 and PA-Na concentration from 30 to 50 mg/L. IR

Selective flotation of scheelite from calcite and fluorite

Mar 01, 2015· 1. Introduction. The flotation separation of scheelite from other calcium-containing minerals such as fluorite and calcite, is problematic, due to their similar solubility and the same active Ca 2+ site for interaction with anionic collectors (Rai et al., 2011).Thus, using a single type of collector is unlikely to achieve selective flotation of scheelite from fluorite and calcite.

A significant improvement of fine scheelite flotation

Jul 01, 2019· The scheelite raw ore used in this study was obtained from the overflow of the ball mill in the flotation plant of XinTianling Mining concentration in Chenzhou, China, with a WO 3 grade of 0.20 wt%. The multi-elementary analysis results of the run-of-mine ore are shown in Table 1.The only tungsten mineral was scheelite, and was associated with calcite, garnet, feldspar, muscovite.

FLOTATION SEPARATION OF SCHEELITE FROM FLUORITE

Keywords: scheelite, fluorite, calcite, regulator, flotation separation . INTRODUCTION . In scheelite flotation, gangue minerals such as Fluorite and Calcite have the same surfaceactive cation (Ca-2+ ) with scheelite minerals and strong binding capacity with the fatty acid collectors. So the flotability of scheelite

A Highly Selective Reagent Scheme for Scheelite Flotation

Previous studies have proved that the lead complexes of benzohydroxamic acid (Pb–BHA) are effective collectors of scheelite flotations; however, the separation of scheelite from calcite needs depressants with high selectivity. In this study, we reported a novel depressant for calcite minerals, and Pb–BHA served as the collector of scheelite. The flotation behavior of polyaspartic

Enhanced electronic effect improves the collecting

Jun 15, 2020· 1. Introduction. Scheelite is a principal tungsten mineral and the main source of tungsten metal in China. In recent years, using hydroxamic acids as collectors has been the convenient approach for the selective flotation of scheelite in complex calcium minerals flotation (Kupka and Rudolph, 2018, Yang, 2018).It is worth noting that the chelation reaction between benzohydroxamic acid (BHA

Different Flotation Performance of Ultrafine Scheelite

In industrial practice, hydrodynamic cavitation (HC) is commonly triggered by jetting either reagent solution or pulp. Although both methods can enhance mineral flotation, are their roles the same? There are few research studies in the field, which severely limits our understanding on mineral flotation combined with HC. Therefore, in this study, the flotation of ultrafine scheelite with HC
