Embodiment 1

[0023] For a titanium-containing magnetite in Shaanxi, its main minerals are titanomagnetite and ilmenite; metal sulfides are mainly pyrite; stone, biotite, sericite and sphene. The ore is a sparse scattered disseminated structure, in which the minerals titano-magnetite and ilmenite have undergone strong chloritization or spheneization, titanium and iron are closely symbiotic, and the intercalation relationship between minerals is complex. The mineral is treated as follows:

[0024] 1. After crushing the ore, carry out weak magnetic separation with a magnetic field strength of 1800 gauss to obtain magnetic separation concentrate I and magnetic separation tailings; magnetic separation tailings are subjected to strong magnetic tailing with a magnetic field strength of 0.8T to obtain magnetic separation concentrate II and tailings X;

[0025] 2. Grinding the magnetic separation concentrate Ⅰ and magnetic separation concentrate Ⅱ, the grinding fineness is controlled at about 70%...

Abstract

The invention discloses a method for preparing dense-medium fine powder through titaniferous magnetite with iron and titanium coexisting tightly. Through a three-stage magnetic separation and flotation operation and by controlling orderly conduction of all steps and comprehensively control matching of parameters, the dense-medium fine powder with good economic value is finally obtained. A new way is provided to process the titaniferous magnetite with iron and titanium coexisting tightly, the titaniferous magnetite with iron and titanium coexisting tightly is used for preparing the dense-medium fine powder, and comprehensive utilization of resources is effectively realized. The method has the advantages of being simple in technological process, good in effect and free of pollution, making waste profitable and the like.

Description

technical field [0001] The invention belongs to the field of comprehensive metal recovery and utilization, and in particular relates to a method for preparing dense medium micropowder by utilizing titanium-containing magnetite which is closely symbiotic with iron and titanium. Background technique [0002] my country is rich in iron and titanium resources, but the resources are generally of low grade and cannot be directly utilized without beneficiation. Nowadays, the recovery process of ilmenite, vanadium-titanium magnetite, and titanium magnetite for iron and titanium is usually: first extract iron through magnetic separation, and then enrich titanium through magnetic separation-flotation process. Separating iron and titanium and recycling them separately is an effective way to utilize ilmenite, vanadium-titanium magnetite and titano-magnetite resources. However, in the north of my country, there is a titanium-containing magnetite resource with close symbiosis of titanium...
