long been known for ex tracting magnesia from dolomite for the purpose of separating the two ingredients of the dolomite, lime andmagnesia. most of these processes are based on brosche alexander 4 1929magnesium processing techniques &methods britannicaextraction and refining. a strong chemical reagent, magnesium forms stable compounds and reacts with oxygen and chlorine in both the liquid and gaseous states. this means that extraction of the metal from raw materials is an energyintensive process requiring welltuned technologies. on dolomite extraction issue: denr blames cebu system the sep 10, 2020 · the department of environment and natural resources yesterday washed hands of the dolomite extraction controversy, attributing it instead to a problem with the cebu system since such dolomite: a sedimentary rock known as dolostone or dolomite rockdolomite, also known as \\"dolostone\\"and \\"dolomite rock,\\"is a sedimentary rock composed primarily of the mineral dolomite, camg(co3)2. dolomite is found in sedimentary basins worldwide. it is thought to form by the postdepositional alteration of lime mud and limestone by magnesiumrich groundwater. see full list on geology.com dolomite is very common in the rock record, but the mineral dolomite is rarely observed forming in sedimentary environments. for this reason it is believed that most dolomites form when lime muds or limestones are modified by postdepositional chemical change. dolomite originates in the same sedimentary environments as limestone warm, shallow, marine environments where calcium carbonate mud accumulates in the form of shell debris, fecal material, coral fragments, and carbonate precipitates. dolomite is thought to form when the calcite (caco3) in carbonate mud or limestone is modified by magnesiumrich groundwater. the available magnesium facilitates the conversion of calcite into dolomite (camg(co3)2). this chemical change is known as \\"dolomitization.\\"dolomitization can completely alter a limestone into a dolomite, or it can partially alter the rock to form a \\"dolomitic limestone.\\"see full list on geology.com dolomite is slightly harder than limestone. dolomite has a mohs hardness of 3.5 to 4, and limestone (composed of the mineral calcite) has a hardness of 3. dolomite is slightly less soluble in dilute hydrochloric acid. calcite will effervesce vigorously in contact with cold, dilute (5%) hydrochloric acid, while dolomite produces a very weak effervescence. see full list on geology.com these differences are often not significant enough to make a positive identification in the field. distinguishing the rocks in the field is further complicated by a compositional continuum that ranges from limestone to dolomitic limestone to dolomite. a chemical analysis that determines the relative abundances of calcium and magnesium is needed to accurately name the rocks. see full list on geology.com some geologists are uncomfortable using the word \\"dolomite\\"for both a mineral and a rock of the same composition. they instead prefer using \\"dolomite rock\\"or \\"dolostone\\"when speaking of the sedimentary rock and \\"dolomite\\"when speaking of the mineral. although these terms simplify communication and improve accuracy, many geologists continue to use the word \\"dolomite\\"for both the mineral and the rock. see full list on geology.com if you examine the photo of granular dolomite, you will see that the rock is composed of easily recognizable dolomite crystals. the coarse crystalline texture is a sign of recrystallization, most often caused by metamorphism. dolomite that has been transformed into a metamorphic rock is called \\"dolomitic marble.\\"see full list on geology.com dolomite and limestone are used in similar ways. they are crushed and used as an aggregate in construction projects. they are kilnfired in the manufacture of cement. they are cut into blocks and slabs for use as a dimension stone. they are calcined to produce lime. in some of these uses, dolomite is preferred. its greater hardness makes it a superior construction material. its lower solubility makes it more resistant to the acid content of rain and soil. in the chemical industry, dolomite is used as a source of magnesia (mgo). the steel industry uses dolomite as a sintering agent in processing iron ore and as a flux in the production of steel. in agriculture, dolomite is used as a soil conditioner and as a feed additive for livestock. dolomite is used in the production of glass and ceramics. dolomite has been used as a minor source of magnesium, but today most magnesium is produced from other sources. see full list on geology.com jp2013256685a method for extracting magnesium from dolomite problem to be
