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.

2016-4-1  Literature results discussed earlier for the selective separation of sodium feldspar from potassium feldspar seems to employ only HF medium. The first mechanism on fluoride activation of feldspar at low pH has been given by Buckenham and Rogers. They proposed that fluoride gives rise to sites of charged aluminum/fluoride complexes at the mineral surface on which cationic collectors adsorbs. Second explanation was given by Smith who investigated the activation of beryl and feldspar with fluoride in cationic collector systems; He proposed that fluoride

(PDF) EXTRACTION OF POTASH FROM K-FELDSPAR MINERAL

Feldspar exists in different phases such as microcline, albite and anorthosilicate. The feldspar has an average chemical composition of 62% SiO2, 26% Al2O3, 8% K2O, 3% Na2O and 1% CaO as the main constituents. In order to extract potassium, chemical leachants such as HCl, H2SO4 and HNO3 were tried with different concentrations.
