Titanium Ore Processing: Magnetic Separation and Flotation

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+flotation process

After crushing and grinding the raw ore, the magnetite is first selected using weak magnetic separation. After the tailings continue to undergo magnetic separation and sweeping, titanium minerals are recovered from the magnetic separation tailings using flotation method.

Process features

 simple equipment and low dosage of chemicals.

Typical beneficiation plant

The main metal minerals in the ore of Panzhihua Titanium Preparation Plant include titanium magnetite, ilmenite, magnetite, pyrrhotite, pyrite, etc., while the gangue minerals mainly include titanium pyroxene, plagioclase, olivine, etc; The ore is first subjected to iron selection operations, and the tailings from the iron selection enter the titanium selection workshop. The process of selecting titanium in the workshop is as follows:
