New technological solutions for the beneficiation of synnyrites

New technologies for processing high-potassium alumopotassium raw material (synnyrites) on the basis of the previously established possibility of sepa rating aluminosilicates with similar cations are substantiated. A combined scheme including chemical, flotation and magnetic beneficiation that provid es the production of kalisilite and microcline concentrates is suggested. T he kalisilite concentrate is a new chlorine-free potash fertilizer and the high quality feldspar concentrate is a scarce raw material for the porcelai n-faience, electrical engineering, and refractory industries.
