Gravity beneficiation technology for titanium tailings

With the increasing demand for titanium metal, the mining output of titanium tailings is also increasing year by year. The titanium metal content in titanium tailings is often low and requires purification through mineral processing technology. Among them, gravity beneficiation technology is a common beneficiation method. This article will introduce the operating steps and precautions of gravity beneficiation technology for titanium tailings.

1、 The principle of gravity beneficiation technology

Gravity beneficiation technology is a method of separating materials by utilizing their different forces in the gravity field. In the gravity beneficiation of titanium tailings, a combination of flotation and gravity separation is usually used. Firstly, the titanium minerals in titanium tailings are separated from other impurities through flotation to obtain a titanium containing flotation concentrate. Then, the titanium minerals in the concentrate are further purified through gravity separation to obtain high-grade titanium ore.

2、 The operating steps of gravity beneficiation technology

1. Grinding of titanium tailings

Grind the titanium tailings to achieve Granularity suitable for flotation and gravity concentration.

2. Flotation

Immerse the ground titanium tailings into the flotation cell, add flotation agent and foam agent to separate titanium minerals from other impurities. In the flotation process, it is necessary to control the amount of flotation agent and foam agent, as well as the stirring speed and flotation time of the flotation cell to achieve the best separation effect.

3. Reselection

Feed the flotation concentrate into the gravity separator for gravity separation. Gravity concentrators typically use equipment such as gravity concentrators, spiral separators, and centrifuges. In the process of gravity separation, it is necessary to select a suitable gravity separator for operation according to the density, magnetism and other characteristics of titanium minerals. At the same time, it is also necessary to control parameters such as the feed volume, water volume, and sorting speed of the gravity separator to ensure the sorting effect.

4. Concentrate processing

The titanium ore obtained through gravity separation also requires concentrate treatment to meet the requirements of industrial production. Usually, methods such as magnetic separation, electrical separation, and flotation are used for concentrate treatment to improve the grade and recovery rate of titanium ore.

Notes on Gravity Beneficiation Technology

1. The amount of flotation agent and foam agent should be appropriate. Too much will affect the flotation effect, and too little will not achieve the separation effect.

2. The stirring speed and flotation time of the flotation cell should be well controlled to ensure the separation of titanium minerals from other impurities.

3. The selection of gravity separators should be determined based on the characteristics of titanium minerals, and different gravity separators have different sorting effects.

4. The method of concentrate treatment should be determined based on the grade and recovery rate of titanium ore to achieve the best treatment effect.

In summary, titanium tailings gravity beneficiation technology is a commonly used beneficiation method, which can effectively improve the grade and recovery rate of titanium ore by combining flotation and gravity separation. During operation, attention should be paid to the consumption of flotation agent and foam agent, the stirring speed and flotation time of flotation cell, the selection of gravity separator and the method of concentrate treatment. Only by mastering the correct operating steps and precautions can the efficiency, stability, and reliability of titanium tailings gravity beneficiation technology be guaranteed.
