Rough selection and sweeping in beneficiation

The principle of rough selection and sweeping in beneficiation is to separate the useful minerals from the gangue minerals through different physical and chemical properties.

The process typically involves three stages:

1. crushing and grinding the raw ore to reduce its size,
2. separating the useful minerals from the gangue through processes such as gravity separation, magnetic separation, flotation, and leaching, and
3. further refining and processing the extracted minerals to make them suitable for commercial use.

A table for rough selection and sweeping in beneficiation would typically include the following columns:

1. Material type: This column would identify the type of material being processed, such as iron ore, copper ore, gold ore, etc.
2. Screen size: This column would indicate the size of screen being used for rough selection and sweeping. Screens are used to separate the material into different sizes.
3. Feed rate: This column would identify the rate at which the material is being fed into the beneficiation process.
4. Concentrate grade: This column would show the grade of the concentrate that is being produced as a result of the rough selection and sweeping process. The concentrate is the portion of the material that is enriched with the desired mineral.
5. Recovery rate: This column would indicate the percentage of the mineral that is being recovered from the material as a result of the rough selection and sweeping process.
6. Remarks: This column would allow for any additional comments or observations related to the beneficiation process, such as any issues that arise or recommendations for improvement.

There are various tools and equipment used in the process, such as crushers, mills, classifiers, flotation machines, magnetic separators, and leaching tanks.

For learning more about rough selection and sweeping in beneficiation, you can refer to books on mineral processing, such as "Mineral Processing Plant Design, Practice, and Control" by Mular, Gupta, and Yan, or "Introduction to Mineral Processing" by Kelly and Spottiswood.
