Flotation Separation Of Feldspars From Quartz

Selective Flotation Separation of Feldspar in Non Fluoride ...

In the conventional flotation separation of feldspar-quartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector. The bulk of amine collectors used in current feldspar operations are applied as the water-soluble acetates of the free-base amines.

Flotation of quartz from quartz-feldspar mixtures by the ...

Flotation experiments performed on a quartz-feldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric acid (HF) simply by the aid of a frother. High grades and good recoveries were obtained for both quartz and feldspars. A feldspar concentrate of 99.9% at a recovery of 95.6% was produced.

successful quartz separation. Prior to flotation, the samples had been crushed, screened and deslimed, and consisted almost entirely of qtartz and feldspars. Consequentll, fresh stone surfaces, a narrow size range, and simple mineralogy were assured. rf these conditions are not met the

Systematic review of feldspar beneficiation and its ...

The zeta potential of the feldspar becomes more negative with the addition of EDTA at pH 2, and the separation of feldspars from quartz is enhanced in the batch cell flotation tests. But the low pH condition may cause a challenge on the wastewater.

US3844939A - Flotation separation of feldspar - Google Patents

An improved process for separating feldspars from feldspathic ores by means of froth flotation wherein a combination of a higher aliphatic amine salt and a higher aliphatic or aromatic sulfonate is used as a flotation reagent, eliminating the necessity for activation with hydrofluoric acid.

Review of flotation of feldspar | Request PDF

Feldspars can be floated by reverse floatation method from the spodumene float quartz tails by conditioning the slurry with hydrofluoric acid and adjusting the pH to 2-2.5, adding tallow amine ...


Keywords: Feldspar, Selective separation, Weathered granites, Flotation, Monovalent salts Granite and granodiorite deposits are widely scattered throughout in Eastern Black Sea region of Turkey. These granitic bodies also contain considerable amounts of quartz, Na-feldspar, K-feldspar, mica and other color-imparting ferruginous impurities.
