How to tell quartz from white feldspar in rocks. If you are looking at a rock and you are unsure whether you are seeing quartz or white feldspar, you can try the following: Look for cleavage. If the mineral has cleavage, it is most likely feldspar. If it does not have cleavage, it is most likely quartz. Try to scratch the mineral with a piece ...

Comparing the Properties of Feldspar and Quartz. Although feldspar and quartz are both silicate minerals, their physical properties are different. Quartz ranks higher on Mohs hardness scale, that is, at 7, and feldspar is rated as 6. Moreover, the conchoidal fracture of quartz is basically different from that of feldspar cleavage.

For feldspar/quartz separation, the best feldspar concentrate was obtained using 582 g/t quaternary ammonium salt solution as a collector and 2000 g/t HF as an activator/depressant at an acidic medium of pH 2.5, and at 1200 rpm impeller speed. Fig. 2. Flowsheet for obtaining a feldspar concentrate.

3. Flotation separation method is suitable for separating quartz ore associated with feldspar ore. 4. Electric separation: This method is more common in beneficiating fine-grained quartz sand. 5. Combined quartz beneficiation processes are usually used to achieve the best separation effect in the actual application.

quartz (i-Minerals inc., 2017b). in 2016, pilot-plant work by an independent laboratory resulted in a potassium feldspar product with 13% to 14% potassium oxide (K 2 O) and low iron [0.03% ferric oxide (Fe 2 O 3)] content (i-Minerals inc., 2017a). the company produced small quantities of feldspathic (feldspar-quartz) sands from its WBl tailings ...

Feldspar Ore Grinding. The Rod Mill is standard for grinding feldspar ore, producing a granular product with a minimum of slime and fine size material. Grinding is always done to minus 20 mesh on account of market requirements. Feldspar this coarse will float very nicely and if liberation is obtained at this size no further grinding is necessary.
