Influence of high concentration Zn2+ on floatability of ...

2021-7-1  The influence of high concentration Zn 2+ on the floatability of sphalerite in an acidic system was investigated via flotation experiments, zeta potential measurements, contact angle measurements, and X-ray photoelectron spectroscopy. The results indicated that Zn 2+ was adsorbed on the sphalerite surface and a Zn-hydroxyl complex was formed at a pH of 4 and a Zn 2+ concentration of 4×10 −2 ...

Effects of high Mg2+ concentration on KCl flotation: Part ...

2007-6-1  For example, KCl fails to float once the concentration of potassium ions in solution reaches a critical level. It appears the higher concentration of K + ions in solution has reversed the charge on the KCl, thus stopping flotation. For a sylvinite (KCl–NaCl) – carnallite (KCl Ca (Mg)Cl 2 6H 2 O) ore, the question remains, does a high ...
