Abstract
In order to improve the sorting index of a titanium plant in Panzhihua,a new collector ZF-02 was developed to deal with the fine ilmenite.A closed-circuit flow sheet comprising one roughing,one scavenging and three stages of cleaning,with using ZF-02 as a collector,sulfuric acid as pH value regulator and oxalic acid as a depressant,was adopted to deal with the mass fraction 22.85% of ilmente ore,resulting in an ilmenite concentrate with grade of 48.08% TiO2 and recovery of 89.73%.Compared with MOH in production,ZF-02 not only has the advantages of good performance and price ratio,but also stable foam,a wide range of sources,non-toxic harmless (does not contain benzyl arsonic acid).
