Potash Feldspar Recovery Process - 911 Metallurgist
Jun 29, 2017 Producing feldspar and quartz concentrates from sample COB was difficult. Variations were made in the citric acid-Na2 CO3-fatty acid method as shown in figure 4. The resultant quartz concentrate was of high quality; it contained 97.8 pct SiO2 and only 0.017 pct Fe2O3. The feldspar concentrate contained 0.53 pct Fe2O3.
Microwave-Assisted Extraction Of Potassium From K-Feldspar …
Apr 24, 2019 A creative approach for the hydrothermal decomposition of K-feldspar for the extraction of potassium (K) in mixed alkaline solutions containing NaOH and CaO pretreated by microwave was studied. Under the same processing conditions, a systematic comparison of microwave pretreatment and traditional hydrothermal reaction showed that K+ dissolution efficiency was 95% when the mixture …
