2020-6-5 · Fig. 2 shows that the effect of pH on the flotation recovery of spodumene and feldspar using individual collector at dosage of 4 × 10 −4 mol/L. When DS was used as a collector, the recovery of spodumene and feldspar at neutral pH range were high, reaching more than 60 %. Moreover, it can be seen that the recovery of spodumene and feldspar were relatively close throughout the studied pH

1. A froth flotation process for separating feldspar from quartz-feldspar sands ore consisting essentially of the steps of subdividing said ore to produce at least a fraction having a particle size less than about 1 mm, collecting said fraction and washing the same with water to effect desliming, introducing the washed fraction at a solid concentration of about 20-30 wt percent into an aqueous

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 [].However, there is a large amount of chemical activator (HF or NaF) in the flotation

review of flotation of feldspar | semantic scholar

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. Much of the published information on feldspar flotation relates to fundamental studies seeking to

study on flotation mechanism of separation of potassium

Potassium feldspar and quartz are all silicate minerals with frame structure,and have the similar crystal structure and physicochemical properties. Therefore, flotation has become the main method to separate potassium feldspar from quartz. The separation of potassium feldspar from quartz with anion and cation mixed collector was studied in the paper
