What is an industrial, mining and trading enterprise?

Industrial, mining and trading enterprises mainly refer to iron-making, steel-making, ferrous metal casting, steel rolling, ferroalloy smelting and other enterprises. For example:

1, metallurgical enterprise

Metallurgy is a process and technology to extract metals or metal compounds from minerals and make metals into metal materials with certain properties through various processing methods. Metallurgy has a long history, from the Stone Age to the later Bronze Age, and then to the large-scale development of modern iron and steel smelting. The history of human development has merged with the history of metallurgical development. Metallurgical technology mainly includes pyrometallurgy, hydrometallurgy and electrometallurgy. With the successful application of physical chemistry in metallurgy, metallurgy has moved from technology to science, so metallurgical engineering has been established in universities.

2. Steelmaking enterprises

Iron and steel industry is mainly engaged in ferrous metal mineral mining and ferrous metal smelting and processing, including iron, chromium, manganese and other mineral mining and processing industries, ironmaking industry, steel processing industry, ferroalloy smelting industry, steel wire and its products industry, which is one of the important raw material industries in China. In addition, because steel production also involves other industrial categories, such as the mining of non-metallic minerals and products, such as coking, refractories, carbon products and so on. These industrial categories are usually included in the iron and steel industry.

3. Building materials enterprises

Building materials enterprises mainly refer to enterprises engaged in the production and processing of non-metallic mineral products such as cement, cement products, glass (glass fiber), wall materials, ceramics, refractories and graphite. ? Building materials are the general name of materials used in civil engineering and construction engineering. It can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, brick, ceramics, glass, engineering plastics, composite materials and so on.

4. Light industrial enterprises

Light industry refers to light industry products such as pulp and paper, daily machinery, daily silicate, daily chemicals, food and beverage, plastic products, leather fur and products, clothing, shoes and hats, arts and crafts, carpets, toys, daily hardware, daily refined aluminum products, tools and building hardware products, household appliances, stationery, sports goods, furniture, daily sundries, scales, bamboo, rattan, palm grass products, etc.

5. Textile enterprises

Textile is an enterprise involved in cotton spinning, silk processing, hemp spinning, wool spinning and chemical fiber related business. Its types are cotton spinning, silk processing, hemp spinning, wool spinning and chemical fiber, or knitting, weaving and nonwovens. Textile and garment, footwear and headwear manufacturing. ? China textile industry is an industry with high labor intensity and high dependence on foreign countries. China is the largest producer and exporter of textiles and clothing in the world. The sustained and steady growth of textile and clothing exports is very important to ensure China's foreign exchange reserves, international balance of payments, the stability of RMB exchange rate, social employment and the sustainable development of textile industry.
