Till now, majority of studies on processing and beneficiation of feldspar ore focused on removal of those phases which are considered as harmful colouring admixtures in ceramic/glass industries [44,45,46,47]. In order to make the beneficiation process effective and economic, any Fe-, Ti or Mn-bearing phase is considered as harmful.

However, the beneficiation of feldspar ores from other silicate gangues is very difficult owing to their similarities in physical–chemical properties. Hydrofluoric acid (HF), which is the main regulator used in the flotation of feldspar, may cause serious environmental and health-related problems.
