Experimental Study on the Flotation of Gabbro Ilmenite with a Novel Collector

The flotation of a gabbro ilmenite from Panxi area using a novel collector SF was investigated.The effects of collector dosage,p H regulator dosage,depressants types and dosage on separation of ilmenite and gangue minerals were studied.Furthermore,the open and closed circuit experiments for ilmenite flotation were carried out.The results show that the ilmenite can be effectively separated from gangue minerals in the ore obtaining the ilmenite concentrate with grade of 48.06% and recovery rate of 86.36% for TiO₂,through the processes of "one roughing,two scavenging and four cleanings" using SF as the collector.The consumption of the novel collector and cost are lower,which can achieve efficient sorting for gabbro ilmenite.
