flotation separation of feldspars from quartz

It is now possible to free feldspar from all kinds of gangue minerals, e.g. mica, quartz and heavy minerals in addition to separation of both K and Na feldspars from each other [2] [4] . Cationic flotation of feldspar (amine + HF) in presence of NaCl was conducted by CengizDemir of Turkey in 2010 to separate both Na- and K-feldspar [ 3 ] .

Relevant Problems of Quartz Extraction Technology

2019-6-21 · The purpose of quartz flotation process is to remove the non-magnetic associated impurities, such as feldspar, mica. These impurities are similar to quartz in element composition and structure, which is difficult to separate from the quartz. The quartz flotation process can be divided into fluorine flotation process and fluorine-free flotation

Feldspar and quartz did not have an IEP, having negative zeta potentials over the pH range investigated (pH 3–10). This suggests that effective separation using a cationic amine collector, which relies on electrostatic attraction as the basic mechanism of adsorption onto mineral surfaces, would not be possible without the use of a depressant.
