Abstract

Colemanite (2CaO 3B₂O₃ 5H₂O) is one of the commercially preferable borates for many industries, such as agricultural, metallurgical, nuclear and production of fibreglass, borosilicate glasses, soaps, detergents, fire retardants, enamels and frits, used directly or after being transformed to boric acid (H₃BO₃). This paper aims mainly to investigate the practical floatability of colemanite from the Emet deposits of Turkey using a conventional collector and to compare the concentration results with dry magnetic separation tests applied at high intensity.
