2016-10-10 Lab-scale flotation tests were conducted on a muscovite ore (9.1 wt.% muscovite) from an industrial mine to determine the effect of varying concentrations of collector and depressant.The feed was wet ground in a laboratory rod mill at 50% solids for 22.5 min to produce a P 80 of 106 μm ().The cell used was a 3 L Denver flotation cell with several concentrates collected over a period of 5 min 2015-7-27 Adding a de-sliming step to remove fines or adding a cleaner flotation stage may further concentrate the muscovite. The addition of traditional entrainment treatments such as wash water may also help to reduce the recovery of fine gangue.

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. Under optimal flotation conditions, a flotation concentrate was produced at a mass weight of 12.48%, with ash and combustible recovery products at 47.86% and 59.92%, respectively. In graphite ore, sericite is one of the main gangue minerals, and thus it is a major impurity in graphite flotation concentrate [128]. The study of entrainment property of sericite in amorphous 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) 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). 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. Under optimal flotation conditions, a flotation concentrate was produced at a mass weight of 12.48%, with ash and combustible recovery products at 47.86% and 59.92%, respectively. 1990-8-1 A good selectivity between muscovite and siliceous gangue is obtained.

The California ore was a micaceous schist containing about 43 percent muscovite. The ore also contained quartz and chlorite, with minor amounts of biotite and various carbonate minerals. The mica was essentially liberated at 65 mesh.

Sericite also occurs in many base metal ore bodies, and it is often recovered strongly into the final flotation concentrate (Silvester, 2011). It has been hypothesized that liberated sericite may be collected in the froth product by true flotation due to surface hydrophobicity (Blaskett, 1960) or slime coating (He, 2009). 2021-1-13 The muscovite in the ores was completely liberated at 4 to 6 mesh.

Process mineralogy suggests that in the raw ore, 61.63% of molybdenite particles distribute in the <20 μm size fraction, and intergrow with muscovite and pyrite as the co The mica concentrate was obtained by the flotation concentration, while feldspar and quartz were in the flotation underflow.
