| What is iron powder? |
* Answer
| Iron powder is also called iron powder, iron ore (mine containing iron or iron compound) is processed by crushing, grinding, beneficiation, etc. into ore powder called iron fine powder.Iron is present in nature in the form of a compound, especially in the state of iron oxide.In the beneficiation, the magnetic separation method can be utilized, and the treatment is very convenient; however, due to its fine structure, it is less reductive.After long-term weathering, it becomes hematite.They can be divided into many categories, such as Red Hematite, Specular Hematite, Micaceous Hematite, and Red Ocher.(3) Limonite This is an ore containing iron hydroxide.Mostly it is attached to other iron ore.(4) Siderite is an ore containing iron carbonate. The main component is FeCO3, which is blue-gray and has a specific gravity of about 3.8.Most of this ore contains a considerable amount of calcium and magnesium salts.(5) Silicate Iron (SilicateIron) This type of ore is a compound salt. It has no certain chemical formula. The composition varies greatly. It is generally dark green, with a specific gravity of about 3.8. The iron content is very low.Poor iron ore.Because this ore often contains many other relatively expensive metals such as copper, nickel, zinc, gold, silver, etc., it is often used in other metal smelting industries.Raw materials; because it contains a lot of sulfur, it is often used to raise sulfur, and iron has become a by-product.Iron ore origin (1) Domestic China’s iron ore distribution is mainly concentrated in Liaoning, Sichuan, Hebei, Beijing, Shanxi, Inner Mongolia, Shandong, Henan, Hubei, Yunnan, Anhui, Jilin, Heilongjiang, Shanghai, Jiangsu, Zhejiang, Fujian,Jiangxi, Hunan, Guangdong, Guangxi, Hainan, Guizhou, Tibet, Shaanxi, |
