Flotation Process Test of a Micro-fine Particle Ilmenite in Western Panzhihua
In order to recover micro-fine particle ilmenite from the inclined plate overflow sample of the second-stage high-intensity magnetic concentrate in the titanium separation system of a concentrator in Western Panzhihua,according to the characteristics of fine particle size composition and difficult separation and enrichment of raw materials,the properties of raw materials are characterized by mineral composition analysis and chemical multinomial analysis.On this basis,a systematic flotation high-efficiency separation test is carried out.The results show that under the conditions of titanium flotation sulfuric acid total dosage of 5 460 g/t,EMB-5 total dosage of 2 350 g/t and inhibitor EMY-5 total dosage of 700 g/t,the titanium con-centrate with TiO2 grade of 47.00%and TiO2 recovery of 82.39%is obtained by one roughing,one scaveng-ing and four cleaning closed-circuit flotation process.The efficient recovery and utilization of micro-fine il-menite is realized,and the comprehensive utilization rate of vanadium-titanium magnetite is improved,which can provide technical support for the process transformation of concentrator.
