The quartz iso-electric point (iep) is about pH 2 and an extrapolation of microcline curve indicates an iep of about pH 1.5. In general, the iep's of quartz and feldspar minerals are reported at pH 2 and at a slightly lower pH, respectively [19]. It is to be pointed out that in the pH region 1.5–2.0 where microcline floats selectively with ...

This is consistent with the reports that the isoelectric points of quartz and feldspar are about 2.0 and 1.5, respectively (Gulgonul et al., 2008; Vidyadhar and Rao, 2007). ─NH 3 +, which is ...
To overcome this problem, a method to separate quartz and feldspar using the combination of dilute acids and isodynamic magnetic separator was explored. This …
An improved method for producing high-purity quartz (Qtz) and potassium feldspar (Kfs) concentrates was developed using various chemical reagents. Froth flotation experiments on a Qtz–Kfs mixture …
Electrostatic separation is used in many heavy mineral sand operations for the separation of minerals, particularly where other separation means (density, size, magnetic susceptibility) are less effective due to close similarity in such properties, as is experienced with minerals such as rutile and zircon. Electrostatic separation is …
Every mineral species has electrostatic properties that can potentially allow separation in an external electrostatic field. Mineral processing categorises minerals into conductors and non-conductors …
However, the separation of quartz and feldspar must be improved. Therefore, a process-flow scheme can be adopted that uses a combination of ore sorting and electrostatic separation for lepidolite-rich particle preconcentration, followed by flotation concentration.
