Zirconium titanium placer is an important mineral resource widely used in fields such as aerospace, nuclear industry, electronics, and chemical industry. However, zirconium titanium sand contains a large amount of impurities, such as iron, aluminum, silicon, etc., which can affect the quality and effectiveness of zirconium titanium sand. Therefore, the purification and impurity removal technology of zirconium titanium sand ore is crucial.
This article will introduce several common purification and impurity removal technologies for zirconium titanium sand ore, to help readers understand the purification and impurity removal process of zirconium titanium sand ore.
1、 Physical methods
1. Magnetic separation method
Magnetic separation is a common physical method that can be used to separate iron minerals from zirconium titanium placer ore. The principle of magnetic separation method is to use the magnetism of iron minerals to separate them through magnetic force. The specific operation steps are as follows:
(1) Crush zirconium titanium sand ore into small particles.
(2) Put the crushed zirconium titanium sand ore into the magnetic separator.
(3) Turn on the magnetic separator and separate the iron minerals based on their magnetism.
2. Heavy liquid separation method
The heavy liquid separation method is a method of separating substances by density difference, which can be used to separate aluminum minerals in zircon titanium placer ore. The specific operation steps are as follows:
(1) Crush zirconium titanium sand ore into small particles.
(2) Put the crushed zirconium titanium sand ore into a density of 2.85g/cm ³ In Ammonium bromide solution.
(3) Stir the solution until it is well mixed.
(4) After standing for a period of time, the aluminum minerals will be separated according to the density difference.
2、 Chemical methods
1. Hydrofluoric acid method
The hydrofluoric acid method is a common chemical method that can be used to separate silicon minerals from zirconium titanium placers. The specific operation steps are as follows:
(1) Crush zirconium titanium sand ore into small particles.
(2) Put the crushed zirconium titanium sand ore into hydrofluoric acid.
(3) Heat hydrofluoric acid to react with silicon minerals.
(4) Filter the reaction solution and separate the silicon mineral.
2. Sodium carbonate method
The sodium carbonate method is a common chemical method that can be used to separate aluminum minerals from zirconium titanium placers. The specific operation steps are as follows:
(1) Crush zirconium titanium sand ore into small particles.
(2) Put the crushed zirconium titanium sand ore into a sodium carbonate solution.
(3) Heat the sodium carbonate solution to react with aluminum minerals.
(4) Filter the reaction solution and separate the aluminum minerals.
3、 Comprehensive method
In addition to the physical and chemical methods mentioned above, there are also some comprehensive methods that can be used to purify zirconium titanium sand ore. For example, zirconium titanium sand ore can be separated by magnetic separation, followed by chemical treatment using hydrofluoric acid method, and finally subjected to heavy liquid separation. This can separate various impurities from zirconium titanium sand ore and improve the purity of zirconium titanium sand ore.
conclusion
The purification and impurity removal technology of zirconium titanium sand ore is an important link in the processing of zirconium titanium sand ore. Through various technical means such as physical methods, chemical methods, and comprehensive methods, impurities in zirconium titanium placer can be separated, improving the purity and quality of zirconium titanium placer. In actual production, it is necessary to select appropriate purification and impurity removal techniques based on the specific situation of zirconium titanium sand ore to achieve the best purification effect.
