The non-ferrous metal beneficiation industry refers to the industry that extracts and processes non-ferrous metal ores. According to the main products, the industry can be divided into several sub-industries such as aluminum, copper, zinc, lead, nickel, and cobalt. Each sub-industry has a unique production process and market demand, forming a rich and diverse non-ferrous metal ore dressing industry ecosystem.
The upstream of the non-ferrous mineral processing industry mainly includes the mining and preliminary selection stages of ores. The main task of this stage is to provide the raw ore or coarse ore mined from the mine to the mineral processing enterprises. After preliminary processing, these ores enter the production link of the mineral processing enterprises as raw materials.
In the midstream stage, mineral processing enterprises use various technologies and equipment to crush, grind, and sort the raw or coarse ore, and finally produce various metal concentrates. These metal concentrates are the basic raw materials for further ore dressing and production by downstream enterprises.
Downstream enterprises process metal concentrates into various non-ferrous metal products, such as aluminum ingots, copper rods, zinc ingots, etc. These products are widely used in construction, transportation, electricity, electronics and other fields, supporting many important industries in the modern economy.
Traditional ore dressing technology
Early ore dressing technology mainly relied on manual selection and simple mechanical operation. These methods are not only inefficient, but also labor-intensive and cannot meet the needs of large-scale industrial production.
Modern ore dressing technology
With the advancement of science and technology, modern ore dressing technology has gradually replaced traditional methods and realized the automation and intelligence of the production process. These technologies include flotation, gravity separation, magnetic separation and chemical ore dressing.
1. Flotation technology: It is the most widely used beneficiation technology that uses the difference in the floating and sinking properties of different minerals under the action of flotation agents to separate them.
2. Gravity separation technology: It is used to separate minerals based on the difference in mineral density. It is often used to process heavy minerals.
3. Magnetic separation technology: It uses the difference in the magnetic properties of minerals to separate minerals. It is suitable for the separation of strong and weak magnetic minerals.
4. Chemical beneficiation technology: It changes the surface properties of minerals through chemical reactions to achieve separation. It is often used to process difficult-to-separate minerals.
In recent years, the introduction of digital technology and artificial intelligence has brought mineral processing technology into the digital age. Digital mineral processing technology has greatly improved the efficiency and accuracy of mineral processing, bringing profound changes to the industry.
1. Biological mineral processing technology: using microbial metabolites to change the surface properties of minerals and achieve separation, which has the advantages of environmental protection and high efficiency.
2. Intelligent mineral processing technology: combining artificial intelligence and machine learning technology to realize the automation and intelligent control of the mineral processing process.
3. Application of nanotechnology in mineral processing: Nanomaterials have excellent physical and chemical properties and can be used for mineral separation and enrichment to improve mineral processing effects.
