These Processes Can Remove Impurities from Potassium Feldspar
The output of potash feldspar is high, and the flotation effect is better. When grinding, it's recommended to prevent insufficient kinetic energy of particles by over-grinding, and the bubbles interacting with the ore particles cannot break through the surrounding hydration layer, making the target minerals difficult to separate.

A Review on Potash Recovery from Different Rock and Mineral Sources
Amarante et al. studied the beneficiation of a Portuguese feldspar ore by magnetic separation followed by froth flotation with HF or H 2 SO 4 as the pH regulators and commercial amine acetate collectors like Armoflote 820 and 543. They found that a final feldspar concentrates with K 2 O of 13.87% could be enriched from the feed K 2 O value of 4.1%.
