Gravity beneficiation process flow of titanium tailings

Gravity beneficiation process flow of titanium tailings

Titanium tailings are an important mineral resource widely used in fields such as aerospace, shipbuilding, automotive, and chemical engineering. Gravity beneficiation process is a commonly used beneficiation method in the mining and utilization of titanium tailings. This article will introduce the gravity beneficiation process flow and operating steps of titanium tailings for you.

1、 Overview of gravity beneficiation process for titanium tailings

Gravity beneficiation is a physical beneficiation method that utilizes the different settling velocities of minerals with different densities under the action of gravity to separate minerals. The gravity beneficiation process of titanium tailings mainly includes steps such as crushing, grinding, gravity separation, and selection.

2、 Detailed explanation of gravity beneficiation process flow for titanium tailings

1. Crushing

Titanium tailings are generally high hardness ores that require crushing treatment. Crushing equipment generally uses jaw crushers, cone crushers, etc. The particle size of crushed titanium tailings is generally below 10mm.

2. Grinding

Grinding is the process of crushing ore to the required particle size. Titanium tailings grinding equipment generally includes ball mills, rod mills, etc. The particle size of titanium tailings after grinding is generally below 0.074mm.

3. Reselection

Gravity separation is the process of separating the ground titanium tailings ore through gravity beneficiation equipment. Titanium tailings gravity separation equipment generally includes spiral concentrators, flotation machines, etc. The titanium tailings concentrate after re selection contains high levels of TiO2.

4. Selection

Selection is the process of further increasing the TiO2 content of the titanium tailings concentrate after gravity separation through methods such as flotation and magnetic separation. The selected equipment generally includes flotation machines, magnetic separators, etc. The TiO2 content in the selected titanium tailings concentrate can reach over 90%.

3、 Advantages and disadvantages of gravity beneficiation process for titanium tailings

1. Advantages

(1) Wide application range: The gravity beneficiation process of titanium tailings is suitable for various types of titanium tailings ore.

(2) Good separation effect: Gravity beneficiation equipment can separate minerals of different densities, and the separation effect is good.

(3) Simple process: The gravity beneficiation process for titanium tailings is relatively simple and easy to operate.

2. Disadvantages

(1) High equipment investment: Gravity beneficiation equipment has high prices and investment costs.

(2) High energy consumption: In the gravity beneficiation process of titanium tailings, grinding, gravity separation and other processes consume more energy.

(3) Environmental pollution: The wastewater and waste residue generated in the gravity beneficiation process cause certain environmental pollution.

Summary

The gravity beneficiation process of titanium tailings is a commonly used beneficiation method, which has the advantages of good separation effect and wide applicability. However, its shortcomings such as high equipment investment, high energy consumption, and environmental pollution also need to be taken seriously. In practical applications, it is necessary to choose appropriate beneficiation methods based on specific circumstances to achieve the goals of economy, environmental protection, and efficiency.
