Significance Of Ilmenite
Yunnan non-ferrous metal Kingdom, emphasis on the development of non-ferrous metals are naturally more metallurgical technology, efficiency is the effectiveness, the study fills the vacancy of ilmenite microwave reduction for industry by microwave carbothermic ilmenite provide theoretical and methodological guidance. Ilmenite can make by microwave carbothermic reaction rate due to microwave carbothermic reduction of ilmenite can be conducted at a lower temperature, so will greatly reduce the use of energy, to energy-hungry China will undoubtedly have great scientific value and economic value. Believe the research will be used in the industrial field, producing good economic and social benefits.
Titanium iron ore is the oxide mineral of iron and titanium, also known as titanium magnetite, which is the main mineral of titanium extraction.Titanium is heavy, gray to black, with a touch of metallic gloss.Crystals are usually made of plates, and the crystals are lumped together in blocks or grainy.Ingredients for FeTiO3.TiO252.66 % is the main mineral that extracts titanium and titanium dioxide.The trigonal crystal system, which is found in the Chinese iron ore deposit of sichuan, is distributed between magnetite granules or fissures and forms large deposits.The chemical composition of ilmenite is related to the formation condition.It is found in ultrabasic rock,
Titanium iron ore is one of the main titanium minerals.Trigonal crystal, crystal is rare,
They are often irregular, scales, plates, or sheets.The colour is black or steel gray, stripe steel gray or black, when contain hematite pack body, the brown or lignite red.Metal to semi-metallic luster, shell or subshell fracture.Crispy.Hardness 5 ~ 6, density 4.4 ~ 5g/cm 3, density follows composition MgO content decrease or FeO content increases.Weak magnetism.In hydrofluoric acid, the solubility is greater, slowly soluble in hydrochloric acid.When dissolved in phosphoric acid and cooled and diluted, add sodium peroxide or hydrogen peroxide, and the solution is yellowish or orange.The titanium iron ore can be found in various types of rock, and is widely distributed in basic rock and acid rock.It is made from pegmatite, which is large and can be several centimetres.When the mineralized mother rock is destroyed by weathering, the iron ore can be transferred into the sand.
Titanium iron ore is the oxide mineral of iron and titanium, which is the main mineral of titanium extraction.Titanium is heavy, gray to black, with a touch of metallic gloss.Crystals are usually made of plates, and the crystals are lumped together in blocks or grainy.Ingredients for FeTiO3.TiO2 52.66% is the main mineral that extracts titanium and titanium dioxide.The trigonal crystal system, the crystal is often made of plates, and the aggregate is lumpy or granular.Steel gray or iron black, metallic luster, mohs hardness 5 ~ 6, weight 4.7 ~ 4.78, weak magnetism.As a secondary mineral, it is found in igneous rocks and metamorphic rocks, which can also form sand mines.The famous mine is elard lake in Quebec, Canada, and cragro, Norway.The coastal sands are famous for Indian trampanol, Florida, and the east coast of Australia.In China's sichuan panzhihua iron ore deposit, the titanium iron ore is distributed between the magnetite particles and the fissures, forming large deposits.Theory composition (wB %) : FeO 47.36, TiO 52.64.Fe2 and Mg2, and Mn2, can be used in the form of FeTiO3 - MgTiO3 or FeTiO3 - MnTiO3 series.In the case of FeO, the main name of the iron ore mine was MgO, and MnO was the main name of the mine.There are often Nb, Ta, and other similar qualities.Under the condition of > 960 ℃ high temperature, FeTiO3 - Fe2O3 can form solid solution completely.With the temperature drop, at about 600 ℃, FeTiO3 - Fe2O3 solid solution to dissolve, separation of hematite in ilmenite crystal, and ∥ orientational alignment (0001).The chemical composition of ilmenite is related to the formation condition.It is found in ultrabasic rock, the titanium iron ore in the basic rock, the MgO content is higher, and the Nb and Ta are not included.Titanium iron ore in alkaline rock, high in MnO, with Nb and Ta.Titanium iron ore, FeO and MnO are found in acidic rock, and the content of Nb and Ta is relatively high.Iron black or steel gray;Stripe steel gray or black.The hematite is brown or lignite.Metal to semi-metallic luster.Opaque.No cleavage.Sometimes appearing or splitting.Hardness 5 ~ 5.5.Crispy.The relative density is 4.0 to 5.0.Weak magnetism.According to crystallization, stripe, weak magnetism can be different from hematite or magnetite.
Titanium iron ore, often as a secondary mineral, or in the base, ultrabasic rock dispersed in the magnetite to form strips, with the enstatite, plagioclase and other symbiosis.Pegmatitic titanium iron ore is produced in granite pegmatite, with microcline, white mica, quartz, magnetite and other symbiosis.Ilmenite is often enriched in alkaline rocks.Because of its stable chemical properties, it can form alluvial placer, with magnetite, rutile, zircon, monazite and other symbiosis.According to the crystallization, striation, weak magnetism can be different from hematite or magnetite.Ilmenite is the most important mineral of titanium ore.
