2018-11-1  K-feldspars are selectively separated from Na-feldspars at low pH using HF and sulfuric acid (pH 2.5–2.8). Consequently, the products composed of 10.51% K 2 O and 3.02% Na 2 O with a K 2 O/Na 2 O = 3.48 in HF medium and 2.55 in sulfuric acid medium were recovered, which demonstrates that the results obtained using HF are better than sulfuric acid.
