Titanium is an important metal element, which is widely used in aerospace, military industry, shipbuilding, chemical industry, electronics and other fields. The main source of titanium is titanium ore, among which the coastal titanium sand ore is an important titanium ore resource. However, the coastal titanium sand ore contains a large amount of impurities, which need to be processed through the beneficiation process to improve the grade and recovery rate of titanium. This article will introduce the beneficiation process and operating steps of Binhai Titanium Sand Mine.
1. Mineral composition and characteristics of coastal titanium sand ore
Coastal ilmenite is mainly composed of Ilmenite, Magnetite, Hematite, zircon, quartz, feldspar and other minerals. Among them, Ilmenite is the main titanium ore mineral, but its grade is low, generally about 20%. In addition, coastal titanium sand ore also contains a certain amount of iron, aluminum, magnesium and other impurities, which will affect the grade and recovery of titanium.
2、 Mineral processing process flow of Binhai titanium sand mine
The beneficiation process of Binhai titanium sand ore mainly includes grinding, rough selection, selection, tailings treatment, and other links.
grinding is the process of crushing raw ore into a certain particle size, usually using a ball mill for grinding. The purpose of grinding is to break the ore into a certain particle size, which is convenient for subsequent beneficiation operations. In the grinding process of coastal titanium sand mines, wet grinding is generally used, and the grinding fineness is generally around -200 mesh.
2. Rough selection
Coarse separation is the process of preliminarily separating the ground ore, usually using a heavy medium separator for coarse separation. The heavy medium separator is a kind of equipment for separation based on density difference. By adding a heavy medium (such as heavy ore sand) to separate ores, the preliminary separation of ores can be achieved. In the process of coarse separation of coastal ilmenite, heavy ore sand is generally used as the heavy medium to separate Ilmenite and Magnetite.
Selection is the process of further separating the ore after rough selection, usually using two methods: magnetic separation and gravity separation for selection. Magnetic separation is a method of sorting using magnetic differences, which separates magnetic minerals from non magnetic minerals through a magnetic separator. In the magnetic separation process of coastal titanium sand mines, a combination of weak magnetic separation and strong magnetic separation is generally used for magnetic separation. Gravity separation is a method of separating heavy minerals and light minerals by using density difference. In the process of gravity separation of coastal ilmenite, the spiral separator is generally used for gravity separation to separate Ilmenite and zircon.
4. Tailings treatment
Tailings treatment is the process of treating the tailings generated during the beneficiation process, usually using methods such as flotation and magnetic separation. In the tailings treatment process of coastal titanium sand mines, flotation method is generally used to separate non-metallic minerals such as quartz and feldspar from the tailings.
The beneficiation process of coastal titanium sand ore is a process of separating impurities from titanium ore to improve the grade and recovery of titanium. The process flow includes grinding, rough selection, selection, tailings treatment, and other links, each of which has its own specific operating steps and equipment. Through the treatment of this process flow, titanium ore minerals such as Ilmenite and zircon can be separated from the coastal titanium sand ore, improving the grade and recovery rate of titanium, and providing an important resource guarantee for the application of titanium.Mineral processing process flow of Binhai titanium sand mine
