II. Operating Steps for Pre concentration and Enrichment of Binhai Zirconium Titanium Ore
1. Crushing and screening of ore
Firstly, it is necessary to crush and screen the coastal zirconium titanium ore into different particle sizes. Usually, equipment such as jaw crushers and cone crushers are used for crushing, and then a screening machine is used to screen the ore to obtain different particle sizes of ore particles.
2. Reselection
Gravity concentration is one of the important methods for preconcentration and enrichment of coastal zircon and titanium ores. Its basic principle is to use the density difference of ore particles for separation. In the gravity separation process, it is first necessary to mix the ore particles with water to form a suspension. Then, through the action of gravity, centrifugal force, and other forces, the denser minerals sink and the less dense impurities float, thus achieving separation. The gravity separation equipment mainly includes gravity concentrators, centrifugal concentrators, etc.
3. Magnetic separation
Magnetic separation is a method of separation that utilizes the differences between magnetic and non magnetic minerals. In the magnetic separation process, it is first necessary to mix ore particles with water to form a suspension. Then, through the action of a magnetic field, magnetic minerals are attracted, thereby achieving separation. Magnetic separation equipment mainly includes wet magnetic separators, dry magnetic separators, etc.
4. Flotation
Flotation is a method of separation that utilizes the physical and chemical properties of mineral surfaces. In the flotation process, it is first necessary to mix the ore particles with water to form a suspension. Then, a flotation agent is added to form bubbles between the useful minerals and the flotation agent, thereby achieving separation. The flotation equipment mainly includes mechanical flotation machines, air flotation separators, etc.
5. Chemical methods
Chemical methods mainly include leaching, dissolution, reduction, etc. In chemical methods, acid leaching, alkali leaching, oxidation leaching, and other methods are usually used to dissolve useful minerals in the ore, and then through reduction, precipitation, and other methods, the useful minerals are separated and enriched.
3、 Precautions for Preconcentration and Enrichment of Binhai Zirconium Titanium Ore
1. The processing of ore should follow scientific methods and operating procedures to ensure safe operation and the improvement of ore grade.
2. Different pre concentration methods are suitable for different ore types and particle sizes, and suitable methods need to be selected based on actual situations.
During the pre-selection enrichment process, attention should be paid to controlling various parameters, such as the amount of flotation agent, magnetic field strength, suspension concentration, etc., to ensure the effectiveness and stability of the operation.
Summary
Pre beneficiation and enrichment of coastal zirconium titanium ore is an important process that can improve ore grade and recovery rate, providing high-quality raw materials for subsequent smelting and processing. This article introduces the basic principle and operational steps of pre concentration and enrichment of coastal zirconium titanium ore, hoping to help readers understand the basic knowledge and operational skills of this process. At the same time, we also remind readers that scientific methods and operating procedures should be followed to ensure the safety and effectiveness of operations during the pre beneficiation and enrichment process of coastal zirconium titanium ore.
