2021-1-15  As a common gangue mineral in copper ore flotation; muscovite is often suppressed in flotation to improve the quality of copper concentrate and achieve the efficient separation of target minerals and gangue minerals such as muscovite (Xu et al., 2013, Smith and Bruckard, 2007).

Influence of metal ions on muscovite and calcite flotation

2019-3-5  To solve these problems, pre-concentration of vanadium-bearing muscovite from stone coal before acid leaching is an effective method. Researches on the pre-concentration of vanadium-bearing stone coal by direct flotation of muscovite have been reported [1,5]. The grade of vanadium in the concentrate can be improved.

1990-8-1  A good selectivity between muscovite and siliceous gangue is obtained. A final product containing 95% muscovite with an overall recovery of 75% is obtained when the flotation concentrate is subjected to magnetic separation. These studies indicate the possibility of separating muscovite from biotite by using a mixture of collectors.

2014-9-6  Flotation experiments were performed to investigate the separation of muscovite and quartz in the presence of dodecylamine (DDA), tallow amine (TTA) and dodecyltrimethylammonium bromide (DTAC). The adsorption mechanisms of these three kinds of amines on muscovite and quartz were studied by FT-IR spectrum analysis, contact angle measurement and molecular dynamics (MD)

Specific Refractory Gold Flotation and Bio-Oxidation

Arsenopyrite, muscovite, and pyrite were upgraded for the two flotation concentrates to different extents. One concentrate was predominated by dolomite (hereafter referred to as dolomite-containing flotation concentrate—DC) whilst the other was predominated by apatite (hereafter referred to as apatite-containing flotation concentrate—AC).

Adsorption mechanism of mixed anionic/cationic

2014-10-1  The flotation performances of muscovite and quartz had been studied using DDA, NaOL and mixed NaOL/DDA with various molar ratios. Fig. 1 shows flotation recoveries of muscovite and quartz as a function of pH in the presence of different collectors. It can be seen that with an increase of pH from 2 to 11, the recovery of muscovite is reduced from 94% to about 40% in presence of DDA.
