feldspar and quartz machinery for seperation

Developing Effective Separation of Feldspar and Quartz

Previously, a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al. [] in an acidic environment (pH = 2.1).It was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a high-quality quartz

A SIMPLE METHOD TO SEPARATE QUARTZ AND FELDSPAR

isolate quartz from feldspar. The procedure is based on the difference in hardness of both minerals. The quartz hardness is between 7-7.5 on the Mohs’ scale, while the feldspar hardness is normally lower (6-7). The friction between quartz and feldspar should result in breaking up feldspar grains into particles of smaller size, while leav-

Use of magnetic separation for purifying quartz for

purified quartz contains no measurable feldspar, concentrated (40-48%) hydrofluoric acid (HF) is typically used to dissolve the remaining feldspars and at the same time etch the quartz. An alternative method for removing heavy minerals and most feldspars is magnetic separation. Whilst this is not a new procedure (Rosenblum, 1958), the use of

Re-examination of common extraction and purification

quartz samples contained small amounts of feldspars (3– 10%), indicating that neither density separation nor mag-netic separation can fully remove all feldspars, and that HF etching is essential. SEM/EDS mapping also showed that the alkali feldspar extracts contained some quartz grains (˘5%). Roughly15% Na-rich grains were observed within

Feldspar Beneficiation & Flotation Process

Apr 14, 2016· The problem in feldspar flotation is to recover slime free granular products, all minus 20 mesh, usually with not over 10% finer than 200 mesh. Flotation under these conditions is critical and pulps are abrasive as well as corrosive. Action of the feldspar pulp must be counteracted by proper selection of equipment to withstand these conditions.
