For solving the difficulty in separation between zircon and rutile, 1-hydroxyethane-1, 1-diphosphonic acid (GS) was independently synthesized, and effects of GS, etedronate sodium (ETD) and amino-trimethylphosphonic acid (ATMP) on flotation of zircon and rutile were also explored. Based on micro-flotation tests, the collecting performance and corresponding mechanism of collectors were analyzed by contact angle measurement, Zeta potential measurement and FTIR spectroscopy. It is found that GS exhibits excellent collection performance and selectivity in separation under neutral conditions, bringing in significant improvement in separation between rutile and zircon. Phosphonic acid group of GS enhances the electronegativity and hydrophobicity by multi-point adsorption, resulting in effective collection. The FTIR analysis has further approved chemical adsorption of phosphonic acid group.
