Nov 12, 2013 Abstract. This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite as well as the separation of the individual feldspar minerals themselves.
amine hydrochloride collectors were used for the flotation of feldspars in presence of HF or a mixture of HF and NaCl. The C 10-12 amine gave the best flotation results 7 8. The feldspar was activated whereas the quartz was depressed by conditioning with HF. A comprehensive review on flotation of mica, iron oxides, ilmenite and

Feldspar processors reported co-product recovery of mica and silica sand. Feldspar is mined from large granite bodies called plutons by geologists, from pegmatites formed when the last fluid stages of a crystallizing granite becomes concentrated in small liquid and vapor-rich pockets that allow the growth of extremely large crystals, and ...

Mica Mineral Flotation. Mica is commonly used as thermal insulation in electrical and electronic applications, as well as in the production of paint, rubber goods, wallboard, roofing material, drilling muds and more. Mica ores are usually found in pegmatites associated with quartz, feldspar
Aug 01, 1990 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. The results indicate ...
The QUARTZ Corps mica products occur in the same area as our quartz products, and offer a number of unique properties including being chemically inert, dielectric, elastic, flexible, hydrophilic, insulating, lightweight, platy, reflective, refractive, and extremely resilient. Mica can be treated to occur in a range of opacities, from fully opaque to transparent. Mica is Read More...
In feldspar flotation, the minerals causing slime formation have similar mineralogical properties to other minerals trying to be floated during the mica and and heavy mineral removal flotation stage. This causes unsuccesful selective separation and also excessive reagent consumption 19 , 27 , 30 , 31 , 32 .
Feldspar recovery in the concentrate, being 86.67 without dewateringwashing increases to 94.58 after three stage dewateringwashing between mica and metal-oxides flotation stages.

Generally speaking, the feldspar concentrate rich in potassium and sodium is recovered by the combined mineral separation methods of gravity separation, electric separation, magnetic separation and flotation to remove associated minerals such as quartz and mica.
For mica minerals, it can be removed under an amine collector with a pulp pH of 2.5-3.5. For silicate minerals, when the pH of the slurry is 3-4, select sulfonate collectors to emerging. Weakly acidic flotation has less reagent consumption than weakly alkaline flotation, and the output of potash feldspar is high, and the flotation

A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate ...

Nov 23, 2020 Flotation is one of the commonly used methods for silica sand beneficiation. It is mainly used to remove mica and feldspar minerals that are symbiotic with silica sand. However, in the actual production process, the flotation process will be affected by many factors, including feed size, slurry temperature, slurry liquid chemical composition, flotation reagents and other flotation conditions.
