The feldspar industry has long sought a mechanical process to replace the inefficient hand sorting of feldspar. A dry mechanical process was developed for removing iron‐bearing impurities from feldspar by means of Rowand‐Wetherill magnetic separators. These separators were replaced with newly‐developed, more efficient induction magnetic separators which produced results never before attained in the industry. Granular feldspar was developed for the glass industry in conjunction with the new process of feldspar preparation. Feldspar with a uniformly low iron content and free from the usual iron‐bearing minerals can now be produced from run‐of‐mine or hand‐selected feldspar.
