Abstract

Abstract

The TiO₂ content of a low grade ilmenite in Panxi is 6.15% and its mineral composition is complex. In order to fully recover ilmenite, mineral processing experiments were carried out. According to the occurrence state and particle size distribution characteristics of titanium, the combined technological processes of pre-tail dumping by strong magnetic separation, quality improvement by gravity separation, iron removal by fine grinding and low intensity magnetic separation, reverse flotation desulfurization and one roughing-one scavenging-two cleaning titanium flotation were formulated. The effects of magnetic induction intensity, magnetic medium size, pulsating stroke, grinding concentration, grinding time, flotation regulator and collector dosage were studied. The experimental results show that after the ore dressing test is carried out by the process of "one strong magnetic throwing tail-two segment redressing-grinding-removing iron-flotation", the TiO₂ grade of 48.22% and the recovery rate of 35.19% can be obtained. The main useful mineral in the ore is ilmenite, which has been effectively recovered.
