Abstract

Cationic ether-diamine collector XL-1 was introduced to the direct flotation process of ilmenite in Midi Titanium Concentration Plant of Panzhihua. A closed-circuit flowsheet comprising one roughing,four stages of cleaning and one scavenging,with XL-1 dosage as 180 g / t at a temperature of 5 ~ 10 ℃,was adopted to treat pulp after removal of sulfur minerals,with the middlings back to circuit in order,resulting in an ilmenite concentrate grading 47. 43% TiO2increased from 20. 38% TiO2in raw ore at a recovery of 69. 30%,with tailings grade decreased to 8. 98% TiO2.
