Apatite vanadium titano-magnetite four-product beneficiation process

Abstract

The invention belongs to the technical field of beneficiation and provides an apatite vanadium titano-magnetite four-product beneficiation process. The process comprises a three-stage crushing procedure, first-stage rod milling and spiral classifier closed loop processing, a magnetic separation sub process, desilicication reverse floatation, dephosphorization reverse floatation, second-stage finesieving, a ferrovanadium beneficiation sub process, third-stage ball milling and fine sieving closed loop processing, mica removing rough floatation, a cyclowash, mica removing cleaner floatation, phosphorus floatation and a titanium beneficiation sub process, wherein the magnetic separation sub process comprises first-stage low intensity magnetic separation, second-stage ball milling and cycloneclosed loop processing, second-stage low intensity magnetic separation and fine magnetic separation. According to the apatite vanadium titano-magnetite four-product beneficiation process, good-qualityconcentrate of the four elements of iron, vanadium, phosphorus and titanium can be obtained at the same time from apatite vanadium titano-magnetite, and natural mineral resources are utilized comprehensively and effectively.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, in particular to a four-product mineral processing process of apatite vanadium-titanium magnetite. Background technique [0002] The main type of iron ore in many iron mines is vanadium-titanium magnetite, and in some areas, vanadium-titanium magnetite is accompanied by a large amount of apatite, that is, apatite-vanadium-titanium magnetite. The ore of this kind of mine generally contains about 15% iron, which is ultra-poor magnetite, P 2 o 5 The content of TiO is generally more than 2%-3%. 2 The content is between 1%-2%, V 2 o 5 The content is 0.3-0.8%. About two-thirds of the iron in this ore exists in the form of magnetite, titanomagnetite and ilmenite, titanomagnetite is generally associated with ilmenite, and the two minerals are contiguous when they are coarse-grained state; the rest of the iron mainly exists in the form of hematite and limonite, and a small amount of iron ...

AI Technical Summary

Problems solved by technology

Therefore, in view of the low iron grade of the ore, it will be difficult to obtain better economic benefits if only iron ore is recovered, which appears to be P 2 o 5 、TiO 2 and effective recovery of vanadium is more necessary
