Gravity beneficiation method for calcium tungsten ore

Calcium tungsten ore is an important type of tungsten ore, with high tungsten content and good grade. It is an important raw material for manufacturing important materials such as hard alloys and tungsten steel. Gravity beneficiation method is a common ore beneficiation method that separates useful minerals from useless minerals in the ore through the action of gravity, achieving the goal of improving grade and reducing costs. This article will introduce the operating steps and precautions of the gravity beneficiation method for calcium tungsten ore.

Introduction to Gravity Beneficiation Method

Gravity beneficiation method is a method of separating minerals by utilizing their different characteristics in the gravity field. Common gravity beneficiation equipment includes gravity beneficiation machines, spiral separators, centrifugal beneficiation machines, etc. Gravity beneficiation method is applicable to the situation with obvious density difference in ores, such as iron ore, copper ore, tungsten ore, etc.

2、 Operating steps of gravity beneficiation method for calcium tungsten ore

1. Ore crushing: Crush the raw ore to meet the particle size requirements of the beneficiation equipment.

2. Ore classification: Classify the crushed ore to remove oversized or undersized ores.

3. Gravity separation: The graded ore is fed into a gravity concentrator for gravity separation. The principle of a gravity concentrator is to separate minerals by utilizing their different settling velocities in water flow. In a gravity concentrator, the ore is impacted by spray water, useful minerals settle to the bottom, and useless minerals are washed away.

4. Re selection: The useful minerals separated by the gravity concentrator are sent to the centrifugal concentrator for re selection. The principle of a centrifugal concentrator is to separate minerals at different settling speeds under centrifugal force. In a centrifugal concentrator, minerals are separated by rotating centrifugal force, useful minerals are collected, and useless minerals are discharged.

5. Precipitation: The useful minerals separated by a centrifugal concentrator are precipitated to remove water and obtain pure calcium tungsten ore.

3、 Precautions for gravity beneficiation method of calcium tungsten ore

1. Requirements for ore particle size: If the ore particle size is too large or too small, it will affect the gravity beneficiation effect, so it is necessary to carry out appropriate classification treatment for the ore.

2. Selection of beneficiation equipment: Different beneficiation equipment is suitable for different types of ores, and selecting appropriate beneficiation equipment can improve beneficiation efficiency.

3. Operating specifications: When using gravity beneficiation methods for calcium tungsten ore, it is necessary to comply with operating specifications to ensure the normal operation of the equipment and avoid accidents.

IV. Conclusion

The gravity beneficiation method for calcium tungsten ore is a common ore beneficiation method, with simple operating steps and significant results. When using gravity beneficiation methods for calcium tungsten ore, attention should be paid to issues such as ore particle size requirements, selection of beneficiation equipment, and operational specifications to ensure beneficiation efficiency and safety.
