Gravity beneficiation process flow of tungsten tin ore

Tungsten tin ore is an important metal ore with extensive applications in industrial production. In order to improve the grade and recovery rate of tungsten tin ore, gravity beneficiation process has become a commonly used treatment method. This article will introduce the process flow and operational steps of gravity beneficiation of tungsten tin ore.

1、 Gravity beneficiation principle of tungsten tin ore

Gravity beneficiation is a method of separating ores by utilizing the different forces of substances in the gravity field. The principle of tungsten tin ore gravity beneficiation is to use the density difference of tungsten tin ore minerals to separate them through gravity beneficiation equipment, so as to achieve the purpose of improving the grade and recovery rate.

2、 Gravity beneficiation process flow of tungsten tin ore

The process flow of gravity beneficiation for tungsten tin ore at includes three stages: rough beneficiation, intermediate beneficiation, and beneficiation.

1. Rough selection

Coarse separation is the stage of preliminary separation of raw ore, mainly using gravity beneficiation equipment to screen and classify the ore, dividing it into different grades according to particle size. At this stage, equipment such as vibrating screens, spiral sorting machines, and heavy media sorting are generally used for processing.

2. Successful selection

Intermediate separation is the stage of further separating the ore after rough separation, mainly using gravity beneficiation equipment for flotation and gravity separation of the ore. At this stage, equipment such as flotation machines and heavy medium sorting machines are generally used for processing.

3. Selected

Selection is the stage of final separation of the ore after being selected, mainly using gravity beneficiation equipment for gravity separation and flotation of the ore. At this stage, equipment such as centrifuges and heavy media sorting machines are generally used for processing.

3、 Operating steps for gravity beneficiation of tungsten tin ore

1. Steps for rough selection

(1) Crush and screen the raw ore to obtain ores with different particle sizes.

(2) Place the ore into a vibrating screen or spiral separator for preliminary screening and grading.

(3) The screened ore is fed into a heavy medium separator for separation to obtain the roughly selected ore.

2. Selection steps

(1) Feed the roughened ore into a flotation machine for flotation separation.

(2) The ore after flotation is fed into a heavy medium separator for gravity separation to obtain the ore after intermediate separation.

3. Selected operation steps

(1) Feed the selected ore into a centrifuge for gravity separation.

(2) The re selected ore is fed into a flotation machine for flotation separation to obtain the selected ore.

4、 Conclusion

The gravity beneficiation process of tungsten tin ore includes three stages: coarse beneficiation, intermediate beneficiation, and selection. By using gravity beneficiation equipment to separate the ore, the grade and recovery rate of tungsten tin ore can be improved. In practical operation, different gravity beneficiation equipment needs to be selected for processing based on the characteristics and process requirements of the ore.
