365体育投注备用 Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite, hematite, goethite, limonite or siderite. The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other item
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). Hematite is also known as "natural ore". The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into iron making blast
365体育投注备用 The natural types of wollastonite ores usually consist of two types: skarn ores and wollastonite quartz calcite ores. The former mainly occurs in the skarn deposit, mineral composition is complex, often associated with quartz, calcite, and diopside garnet skarn minerals; the latter is mainly produced in contact metamorphism and metamorphic deposits, mineral composition is simple, and can be divided into: wollastonite quartz, silicon limestone calcite and wollastonite - quartz - calcite type 3 subtypes. The structure of wollastonite ore usually has two kinds: massive ore with fine-grained granoblastic or nematoblastic texture, dense massive structure, wollastonite form of fine particles, columnar or fibrous aggregates, individual density was very fine jade like; coarse wollastonite fiber with changing crystal structure like, massive and brecciated, porphyritic or banded structure, wollastonite crystal plate is thick, cylindrical, fasciculate or radial (chrysanthemum)
