XX commissioned by Guangxi, Xian Zhou Mining Development Co., Ltd., in September 2007 to October Guangxi XX sulfur iron ore optional test study, and in which aluminum oxide and dioxide The comprehensive recovery test of titanium is aimed at providing a basis for the development and utilization of the mine.
According to the identification of rock ore, Guangxi XX pyrite has higher sulfur and limonite, and bauxite is hydromica -hard boehmite. The main useful mineral is boehmite, accounting for 4-7%. The associated aluminosilicate minerals are mainly composed of hydromica, accounting for 55-70%. Followed by pyrophyllite, kaolinite, sepiolite, and silicon-free minerals have trace anatase. The ore has an aluminum to silicon ratio of about 1.5.
Ore structure: Boehmite has a semi-self-formed scaly structure in bauxite with a particle size of 0.005-0.01 mm. The hydromica is a microscopic scale-like aggregate, or a fine vein-like distribution, which is half in bauxite. Self-formed scaly structure, particle size 0.001-0.01mm, kaolinite, pyrophyllite, mostly small scaly, earthy cryptocrystalline aggregate and colloidal structure, the mine is high in silicon, low in aluminum, available for recycling The aluminum minerals and the aluminosilicates are closely related, so the recovery of aluminum is difficult.
After a large number of tests, the sulfur concentrate can be obtained with 45.94% sulfur and sulfur recovery rate of 91.43%.
Aluminum is recovered from bauxite, and the process of various options such as positive flotation, reverse flotation, roasting and flotation is not enriched.
Anatase, which has not been enriched by the flotation and re-election process, is mainly due to the low content of titanium minerals, fine particle size and close symbiosis with aluminosilicate minerals. related.
Conclusion:
3. Titanium dioxide (anatase) is fine, and a large amount of clay minerals are mixed, which makes it difficult to recycle anatase with heavy flotation.
1. The pyrite mine in Fengshan County, Guangxi Province can obtain 45.50% sulfur concentrate grade and sulfur recovery rate of 91.43% through a coarse, two-fine and two-sweep process.
2. Fengshan County pyrite tailings comprehensively recover aluminum oxide and titanium dioxide. Since the gangue of bauxite is aluminosilicate, the relationship between aluminum and silicon is complicated and the grain size is fine, which is the enrichment of bauxite. The main reason why silicon is not high.
