Industrial, mining and commercial enterprises mainly refers to ironmaking, steelmaking, ferrous metal casting, steel rolling processing, ferroalloy smelting and other enterprises. For example:

1, metallurgical enterprises

Metallurgy is to extract metals or metal compounds from minerals, with a variety of processing methods will be made of metal with certain properties of metal materials and processes. Metallurgy has a long history of development, from the Stone Age to the subsequent Bronze Age, and then to the large-scale development of modern iron and steel smelting. The history of human development incorporates the history of metallurgy. The technologies of metallurgy mainly include pyrometallurgy, hydrometallurgy, and electrometallurgy. With the successful application of physical chemistry in metallurgy, metallurgy has moved from process to science, and so there is a university program in metallurgical engineering.

2, steelmaking enterprises

The iron and steel industry is engaged in ferrous metal mineral extraction and ferrous metal smelting and processing and other industrial production activities of the industrial sector, including metal iron, chromium, manganese and other mineral extraction industry, ironmaking, steelmaking, steel processing industry, ferroalloy smelting, steel wire and its products, and other subsectors, is one of the country's important raw materials industry. In addition, since iron and steel production also involves a number of other industrial sectors such as non-metallic mineral extraction and products, such as coking, refractory materials, carbon products, etc., these industrial sectors are usually included in the scope of the iron and steel industry.

3, building materials enterprises

Building materials enterprises are mainly engaged in cement, cement products, glass (glass fiber), wall materials, ceramics, refractories, graphite and other non-metallic mineral products production and processing enterprises.? Building materials is a collective term for materials used in civil engineering and construction projects. They can be divided into structural materials, decorative materials and certain specialized materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, masonry, ceramics, glass, engineering plastics, composites and so on.

4, light industry enterprises

Light industry is engaged in pulp and paper, daily machinery, daily silicates, daily chemicals, food and beverage, plastic products, leather fur and products, clothing, shoes and hats, arts and crafts, carpets, toys, daily hardware, daily fine aluminum products, tools and architectural hardware products, household appliances, stationery, sporting goods, furniture, daily-use Sundries, scales, bamboo, rattan, palm and grass products and other light industrial products production and business activities of units and places.

5, textile enterprises

Textile is involved in cotton spinning, silk processing, linen spinning, woolen spinning, chemical fiber-related operations and other enterprises. Its type is cotton spinning, silk processing, hemp spinning, wool spinning, chemical fiber, or knitting, weaving, non-woven. Textile clothing, shoes, hats manufacturing.? The textile industry is a highly labor-intensive and externally dependent industry in China. China is the world's largest producer and exporter of textiles and clothing, textiles and clothing exports of sustained and stable growth to ensure that China's foreign exchange reserves, balance of payments, the RMB exchange rate stability, to solve the social employment and sustainable development of the textile industry is crucial.
