Based on results of zeta potential determinations and microflotation tests, bench scale flotation experiments were carried out using spodumene/quartz and lepidolite/quartz synthetic mixtures. Pure natural samples, further purified in laboratory, and commercial reagents were employed. The minerals were characterized by X-ray diffraction technique.

The purpose of quartz flotation process is to remove the non-magnetic associated impurities, such as feldspar, mica. These impurities are similar to quartz in element composition and structure, which is difficult to separate from the quartz. The quartz flotation process can be divided into fluorine flotation process and fluorine-free flotation ...

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 charge densities are comparable on both mica and quartz surfaces (0.40 to 0.48 nm 2), making it possible to draw conclusions on the flotation of quartz from the direct force measurements conducted on mica. Therefore, it may be suggested that, in the pH range of 8.0 to 10.3, the maximum flotation recovery of quartz may be attributed to the ...

A remarkable separation of the quartz from FQA has been realized in an environmental friendly way. The froth flotation results show that the flotation recovery of quartz is 97.79% and that of FQA ...

Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product. Depressing the feldspar and reflotation of the beryl into a high grade marketable concentrate (at least 8.0% BeO) is the usual procedure.

The quartz concentrates from the quartz-feldspar-mica flotation plants in Spruce Pine are further processed to prude the various grades of high purity grade quartz. Little is known about he process except the technology include both flotation and chemical leaching. The technology is proprietary and unpublished.

Froth Flotation The materials used for Froth Floation: ... To efficiently separate feldspar and mica from quartz, we have developed a procedure that makes feldspar and mica hydrophobic and the quartz becomes hydrophilic. By adding a carbonated solution to the sample, we can separate up to …

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.

The QUARTZ Corp's 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...

The following combination, for a North Carolina deposit, involves two steps of flotation. Gangue minerals such as mica, feldspar, and quartz are first floated after grinding the ore and de-sliming by treatment with a cationic collector in alkaline circuit, and with starch or dextrine, to depress spodumene and iron minerals.
