Titanium ore magnetic separation+gravity separation+flotation process

Titanium ore magnetic separation+gravity separation+flotation process

At present, industrial production mainly includes rutile, ilmenite, rutile, and perovskite; Most natural rutile is used for the production of titanium dioxide and metallic titanium, while ilmenite is generally processed and processed into synthetic rutile to produce titanium dioxide and metallic titanium. The beneficiation methods can be divided into two categories: ilmenite beneficiation and rutile beneficiation.

The beneficiation process of ilmenite mainly depends on the deposit and ore properties. The primary ilmenite beneficiation process is mainly divided into two parts: iron beneficiation and titanium beneficiation. Iron beneficiation is mainly carried out through magnetic separation, and the titanium beneficiation process includes magnetic separation, flotation, gravity separation electric separation, gravity separation magnetic separation flotation processes, etc; The beneficiation process of placer ilmenite is divided into two parts: rough selection and selection. Rough selection generally uses ore washing or gravity selection, while selection often uses methods such as magnetic separation and electric separation.
Due to low grade, fine particle size, and high impurities, primary rutile ore is often treated using methods such as gravity magnetic separation, gravity magnetic separation electrical separation, gravity magnetic separation flotation, flotation magnetic separation, as well as roasting and acid washing; Placer rutile is generally progressiveness ore washing or gravity separation, and coarse concentrate is further separated and enriched by magnetic separation, electric separation, gravity separation and other methods.

Magnetic separation+gravity separation+flotation process: After crushing and grinding the ore, the magnetite with strong magnetism is selected by weak magnetic separation. The magnetite tailings are separated into heavy minerals and light minerals through graded gravity separation. Based on the enrichment of titanium minerals in the gravity separation products, flotation is used to further treat the gravity separation products to obtain titanium concentrate.

Process characteristics: high comprehensive recovery rate and high product grade.

Typical beneficiation plant

At the MacIntyre beneficiation plant in the United States, the main useful minerals in the ore are ilmenite and magnetite, while the main gangue minerals are sodium feldspar, hornblende, pyroxene, etc. The specific process is as follows:
