Abstract

The invention discloses a titanium rough concentrate concentration method, and belongs to the technical field of mineral separation. The problems that in the prior art, after concentration, titanium concentrate is low in grade, the content of impurity elements such as silicon and calcium is high, the yield of the titanium concentrate is low, and water and electricity energy consumption is low are solved. According to the titanium rough concentrate concentration method, a raw material bin, a conveying device, a rod mill, a slurry pump pool, a cyclone, a low-intensity magnetic separator, a high-gradient drum-type magnetic separator, a concentrate concentration pool and a belt filter which are sequentially connected are included, and the low-intensity magnetic separator is further sequentially connected with an iron ore concentration pool and the belt filter; and the high-gradient drum-type magnetic separator is sequentially connected with a vertical ring strong magnetic separator, a tailing concentration tank and a diaphragm filter press, an overflow port of the cyclone is connected with a feeding port of the vertical ring strong magnetic separator, and a discharging port of the vertical ring strong magnetic separator is further connected with the slurry pump tank. According to the titanium rough concentrate concentration method, after concentration, about 70% of impurity SiO2, 75% of impurity CaO and 16% of impurity magnesium in the titanium rough concentrate can be removed. The yield of the concentrate can be increased to 87.65%, and the tailing grade is reduced to 15.0%.

Description

technical field [0001] The invention belongs to the technical field of beneficiation, and in particular relates to a method for beneficiating titanium rough concentrate. Background technique [0002] my country is a country with rich titanium resources, and titanium mines are distributed in more than 10 provinces. Titanium resources are divided into 3 types: ilmenite placer, ilmenite rock and rutile rock. Among them, the ilmenite placer is mainly distributed in Guangdong, Guangxi, Hainan and Yunnan provinces. Yunnan is rich in titanium ore resources, including ilmenite ore, titanomagnetite and vanadium titanomagnetite. There are more than 30 proven ilmenite deposits in Yunnan Province, including 15 large deposits, 5 medium deposits and 10 small deposits. Proven ilmenite reserves are 55,160kt, of which high-quality ilmenite reserves are 32,650kt; concentrated in Wuding, Luquan, Maitreya, Dali, Tengchong, Jinghong, and Fumin 6 major areas. Large reserves, high grade, easy ...
