Have their own calculation range. According to the properties and utilization characteristics of minerals, they can be divided into two categories: metallic minerals and nonmetallic minerals.
Main ore varieties
There are many kinds of iron minerals. At present, about 300 kinds of iron minerals and iron-containing minerals have been found, among which 170 kinds are common. But under the current technical conditions, it has been industrialized.
The main utilization values are magnetite, hematite, maghemite, ilmenite, limonite and siderite.
Others: ilmenite, with chemical molecular formula of FeTiO3, Fe 36.8%, Ti 36.6%, O 3 1.6%. Tripartite system. Diamond crystal. Usually irregular particles.
Shaped, scaly or thick. Above 950℃, ilmenite and hematite form complete isomorphism. When the temperature decreases, melting occurs, so ilmenite often contains fine particles.
Small-scale hematite inclusions. The color of ilmenite is iron black or steel gray. The stripes are steel gray or black. Hematite inclusions are brown or reddish brown stripes.
Metallic-semi-metallic luster. Opaque, no cleavage. The hardness is 5 ~ 6.5 and the specific gravity is 4 ~ 5. Weak magnetism. Ilmenite mainly occurs in ultrabasic rocks, basic rocks, alkaline rocks and acidic rocks.
Sex rocks and metamorphic rocks. In Panzhihua vanadium titanomagnetite deposit in China, ilmenite is distributed in granular or flaky form among mineral particles such as titanomagnetite, or along cracks of titanomagnetite.
Plane oriented sheet. Silicate iron is a kind of double salt, which has no certain chemical formula and its composition varies greatly.
Now it is dark green, with a specific gravity of about 3.8 and low iron content, and it is a lean iron ore. Iron sulfide is a kind of ore containing FeS2, which contains
The iron content is only 46.6%, and the sulfur content is 53.4%. Grayish yellow, with a specific gravity of about 4.95 ~ 5. 10. Because this ore usually contains many other more precious metals.
Such as copper, nickel, zinc, gold, silver, etc. , so it is often used as raw materials for other metal smelting industries;
Because it contains a lot of sulfur, it is often used to extract sulfur, but iron has become a by-product, so it can't be called iron ore.
What kinds of iron ore are there? Natural type 1) can be divided into magnetite, hematite, pseudo or semi-pseudo hematite, vanadium-titanium magnetite, limonite, siderite and mixed minerals composed of two or more minerals according to the types of iron-containing minerals. 2) According to the content of harmful impurities (S, P, Cu, Pb, Zn, V, Ti, Co, Ni, Sn, F, As), it can be divided into high-sulfur iron ore, low-sulfur iron ore, high-phosphorus iron ore and low-phosphorus iron ore. 3) According to the structure, it can be divided into disseminated ore, reticulate vein disseminated ore, banded ore, banded ore, dense massive ore, breccia ore, and oolitic, pea-shaped, kidney-shaped, honeycomb, powdery and earthy ore. 4) Gangue minerals can be divided into chronological type, amphibole type, pyroxene type, plagioclase type, sericite chlorite type, skarn type, actinolite type, serpentine type, ankerite type and jasper type iron ores. 2. Industrial type 1) Iron ore that can be used in industry, that is, iron ore in the table, including iron ore for steelmaking, iron ore for ironmaking and iron ore to be selected. 2) Iron ore that cannot be used for industry temporarily, that is, the iron content of off-balance sheet iron ore is between the lowest industrial grade and the cut-off grade.
What kinds of iron ore are there? According to the mineral composition, structure, structure and the characteristics of mining, beneficiation, smelting and technological process, iron ore can be divided into two categories: natural type and industrial type.
1. natural type 1) can be divided into magnetite, hematite, pseudo or semi-pseudo hematite, vanadium-titanium magnetite, limonite, siderite and mixed minerals composed of two or more.
2) According to the content of harmful impurities (S, P, Cu, Pb, Zn, V, Ti, Co, Ni, Sn, F, As), it can be divided into high-sulfur iron ore, low-sulfur iron ore, high-phosphorus iron ore and low-phosphorus iron ore.
3) According to the structure, it can be divided into disseminated ore, reticulate vein disseminated ore, banded ore, banded ore, dense massive ore, breccia ore, and oolitic, pea-shaped, kidney-shaped, honeycomb, powdery and earthy ore.
4) Gangue minerals can be divided into chronological type, amphibole type, pyroxene type, plagioclase type, sericite chlorite type, skarn type, actinolite type, serpentine type, ankerite type and jasper type iron ores.
2. Industrial type 1) Iron ore that can be used in industry, that is, iron ore in the table, including iron ore for steelmaking, iron ore for ironmaking and iron ore to be selected.
2) Iron ore that cannot be used for industry temporarily, that is, the iron content of off-balance sheet iron ore is between the lowest industrial grade and the cut-off grade.
What are the types of graphene ore? Graphene ore, namely graphite ore, is a part of graphite ore body. It has certain quality marks and meets certain requirements of mining technology. The quality of graphite ore includes the meanings of grade, crystallinity and washability.
Generally, the natural types and industrial types of graphite ore are classified according to mineral composition and structure. The former are graphite gneiss, graphite schist, graphite marble, graphite granulite, graphite phyllite, metamorphic coal seam, graphite granite and graphite felsic. The latter are flake graphite ore, aphanitic graphite ore and J- He Kun crystalline ore. In addition, according to the weathering degree, it can be divided into primary ore and weathered ore. Sometimes it can be divided into rich ore and poor ore according to the relative level of grade. The latter two classification habits are used to produce mines.
All kinds of mineral deposits have their own natural graphite ore types. The regional metamorphic graphite deposits mainly develop gneiss, schist, Dali diorite, metamorphic rock and felsic ore, the coal seam contact metamorphic graphite deposits mainly develop slate and phyllite ore, and the magmatic hydrothermal crystalline graphite deposits mainly develop granite, diorite and felsic ore.
What are the biogenetic stones of lead-zinc ore? Lead and zinc are very similar in nature, especially in primary deposits, and often appear in * * *. They have the same source of ore-forming materials, very similar geochemical behavior, similar outer electronic structure, strong sulfur affinity and the same soluble complex. Their adsorption by ferromanganese, clay or organic matter is also very similar. The average lead content in the crust is about 15× 10-6, and the related rocks are sandstone 7× 10-6, carbonate rock 9× 10-6 and shale 20× 10-6. The average content of zinc in the crust is about 80× 10-6, and the related rocks are basalt 105× 10-6, granite 60× 10-6 and sandstone16×/kloc-0.
About 250 kinds of lead-zinc minerals have been found in the earth's crust, and about 1/3 are sulfides and sulfates. Galena and sphalerite are the main industrial mineral raw materials for smelting lead and zinc.
Although more than 250 kinds of lead-zinc deposits have been discovered, only 17 kinds are available for industrial use. Among them, there are 6 kinds of lead industrial minerals 1 1 species and zinc industrial minerals, of which galena and sphalerite are the most important. There are also smithsonite, galena and so on.
Industrial types of ores can be divided into sulfide ores (lead or zinc oxidation rate; 30%), mixed ore (lead or zinc oxidation rate10% ~ 30%); According to the main useful components in the ore, it can be divided into: lead ore, zinc ore, lead-zinc copper ore, lead-zinc sulfur ore, lead-tin ore, lead-antimony ore, zinc copper ore and so on. According to the ore structure, it can be divided into disseminated ore, dense massive ore, breccia ore, banded ore and veinlet disseminated ore.
