muscovite flotation concentrate

Muscovite Flotation by Dodecyl Amine MDPI

Muscovite powder (2 g) was placed in a plexiglass cell. The cell was then filled with distilled water. After 1 min of mixing time, H2SO4 or NaOH was used to adjust the solution pH for 2 min. Collectors were added to the solution, conditioned for 3 min, and collected for 3

Flotation Properties of Muscovite MDPI

Muscovite (50 g) was roasted for an hour at 200, 400, 600, 800 and 1000 C in a muffle furnace with a heating rate of 8 C/min. Micro-flotation experiments of roasted muscovite (2 g) were conducted using a XFG5-35 flotation machine (Wuhan Rock Crush and Grand Equipment Manufacture Co., Wuhan, China) with a spindle speed of 2000 r/min.

Mechanism of separating muscovite and quartz by flotation

muscovite and quartz is below 50 μm, the above methods lead to poor muscovite recovery while flotation may be achieved. It has taken a great deal of research to investigate the flotation of muscovite and quartz [14−18]. General, muscovite can be recovered using cationic collectors, such as amines. Unfortunately, few of them

Mechanism of separating muscovite and quartz by flotation

06-09-2014· 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)

Flotation of mica minerals and selectivity between

Selective flotation of muscovite from a material containing muscovite (15.4%), biotite (13%), and siliceous gangue (quartz and feldspar), using a mixed collector system of sodium oleate and dodecylamine acetate has been described. Muscovite is found to float in preference to biotite, when the pulp is initially conditioned with oleate followed by amine at basic pH values.

Flotation of mica minerals and selectivity between

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.
