1.Iron ore is a mineral containing iron compounds, which is an important part of metallurgical raw materials. Common iron compounds in iron ore are hematite, magnetite, limonite and so on. At present, hematite is one of the most common iron ore in the world, with an iron content of more than 70%. Factors such as the quality of iron ore, mine location and mining cost will affect its application value.
2.Coke refers to the solid carbon material obtained from bituminous coal or anthracite treated by high temperature pyrolysis. The main role of coke is to provide fuel and a reducing agent to reduce the iron compounds in iron ore to iron, and to produce a molten slag. The composition of coke is mainly fixed carbon, other including volatile substances, ash, sulfur, nitrogen and so on.
3.Limestone is a mineral whose main component is calcium carbonate. In the metallurgical industry, limestone is mainly used in steelmaking and metallurgical furnace bottom repair. Limestone can adsorb impurities in the slag, thus purifying the slag.
4.Silica silica is a mineral containing a large amount of silica, mainly used in the manufacture of siliceous materials and alloys. In the metallurgical industry, silica is mainly used in the manufacture of silicon steel and smelting of non-ferrous metals such as copper and nickel, and can also be used to manufacture ferrosilicon alloys and other products.
5.Five, bauxite Bauxite is a mineral containing aluminum oxide, its main component is aluminum oxide, can be used to manufacture aluminum and its alloys. The direct extraction of bauxite is difficult, usually it needs to be burned into aluminum beryllium iron slag first, and then electrolytic extraction.
6.Magnesium raw materials mainly refer to magnesite, magnesite and so on. Magnesium is a light metal, with excellent physical and chemical properties, and has a wide range of applications in aviation, automobile, rail transit and other fields. The metallurgical process of magnesium mainly involves reduction, refining and product manufacturing.
7.Steel waste refers to the waste and waste materials generated in the process of steel production, such as scrap steel, scrap steel, scrap tires and so on. These waste materials are usually recycled to save resources and reduce environmental pollution.
