The mining industry is currently a fast-growing industry, which is not only convenient for mining but also highly profitable. Today, I will give you a brief introduction to the professional terms commonly used in the mining industry. so that you can change from a workplace white to a senior uncle in a second.
1. The position of crushing and ore beneficiation in the mining development production chain: mining, stone crushing, ore beneficiation, smelting, and material processing.
2. Coarse crushing: the first crushing in the crushing process. Generally, the feed size is above 500mm, and the discharge size is below 350mm.
3. Medium crushing: the second crushing in the crushing procedure. Generally, the feed size is below 300mm, and the discharge size is below 100mm.
4. Fine crushing: the last crushing in the crushing procedure. Generally, the feed size is below 150mm, and the discharge size is below 50mm.
5. Raw ore grade: refers to the percentage of the metal content in the raw ore that enters the concentrator for processing in the number of raw ore.
6. Concentrate grade: refers to the percentage of the metal content in the concentrate to the quantity of the concentrate.
7. Tailings grade: refers to the percentage of the metal content in the tailings to the number of raw ore. It reflects the loss of metals in the process of beneficiation.
8. Ore beneficiation: According to the physical and chemical properties of different minerals in the ore, after the ore is crushed and ground, gravity separation, flotation, magnetic separation, electric separation, etc. These methods are used to separate useful minerals from gangue minerals, and separate useful minerals that are symbiotic (associated) from each other as much as possible to remove or reduce harmful impurities to obtain raw materials required for smelting or other industries.
9. The basic process of beneficiation:
(1) Preparatory work: including the crushing, screening, grinding, and grading of raw ore. The purpose is to separate the useful ore from the gangue unit and create conditions for the next step of beneficiation and separation.
(2) Separation operation: With the help of gravity separation, magnetic separation, flotation, and other ore dressing methods, the useful minerals are separated from each other to obtain the final beneficiation products (concentrate, medium, and tailings ore).
(3) Post-selection treatment: including the dehydration of concentrate and tailings, the precipitation, filtration, drying of fine-grained materials, and the clarification and recycling of water.
10. Aggregate: The granular material that plays the role of the skeleton and filling in concrete and mortar. According to the particle size, it can be divided into coarse aggregate and fine aggregate.
Coarse aggregate (stone): Rock particles with a particle size greater than 4.75mm, including pebbles and crushed stones:
Fine aggregate (sand): Rocks and particles with a particle size of less than 4.75mm, including natural sand and artificial sand.
11. Apparent density: the mass of aggregate particles per unit volume (including internal closed pores).
12. Crushing ratio: the ratio of the feed size to the output size in the crushing operation.
