2020-3-29 Pure sodium is a relatively light, silvery and soft metal. This means it is found more frequently in the lighter granites that compose the continental crusts and less frequently in the heavier basalts of oceanic crusts. Pure sodium is produced via chemical processes from sodium compounds, but it is both dangerous and difficult to handle and store.
Read MoreMost sodium is obtained by electrolysis of molten mineral sodium chloride (halite). Some is obtained from trona and soda ash. It occurs in many other minerals as well, including amphibole, zeolite and cryolite. Halite is mined in the USA China, Germany, Russia and Canada.
Read MoreOre deposits may be found in all types of rocks—igneous, sedimentary, and metamorphic—and seawater is also a significant source of such elements as sodium, chlorine, magnesium, and bromine. There are many processes of geochemical
Read More2013-11-30 Sodium is not mined. At least not a sodium. Sodium metal is highly reactive, and as such, it is not found free in nature. It will be found in conbination with another or other elements.
Read More2020-11-1 It is found as an igneous segregation and also in metamorphic rocks and as vein deposits. Often found in sedimentary rocks being both primary and secondary in origin. Often mined for the gold or silver associated with it.
Read MoreIt is found in igneous, metamorphic, and sedimentary rocks. It is associated with many valuable ore deposits as well. Amethyst is a variety of quartz and owes its purple color to the presence of iron. It is composed of silicon dioxide SiO 2.

It is found in the cavities of intrusive and volcanic igneous rocks; often as clear shiny crystals and is associated with calciteand zeolites.
Read MoreRocks are made of minerals. Only a few minerals are rock forming and most rock is made from a combination of the commonest of these such as feldspars, quartz, mica,

Marcasite most frequently occurs as a replacement deposit in limestone and often in concretions imbedded in clays, marls, and shales. Margarite Margarite has the formula CaAl2(Al2Si2))O10(OH)2.
Read MoreIt is found in clay, shale, slate, schist, granite, syenite, and anorthosite. The most important aluminum ore, an iron-containing rock consisting of about 52 percent aluminum oxide, was discovered in 1821 near Les Baux in southern
Read MoreSodium’s name is derived from the English word soda. Much like lithium, sodium is a light, very soft, silvery-white metal. It is even softer than lithium and can be cut with a knife. Sodium is very reactive with air and water. If a sufficient quantity comes in contact with water, sodium can actually explode.

Read MoreCrystals are relatively rare; when found, they are dodecahedral or octahedral. Sodalite occurs in igneous rocks and associated pegmatites. It is sometimes found in contact metamorphosed limestones and dolomites and in rocks ejected from volcanoes. Rare crystals are found
Read More2020-11-1 Found in rocks where the amount of silica in the magma was not sufficient to form feldspar. It is not found, therefore, in rocks that contain quartz. From the Greek word for 'white'. Lime Lime is the common name of calcium oxide. Limestone Limestone is a sedimentary rock composed of calcium carbonate. Limonite Limonite is an iron ore

Sodium A common soft, waxy, light, extremely malleable silver-white unstable metallic element of the alkali group.It is always found as a compound with other elements in nature, such as common salt, albite, etc. . sodium hydroxide - Strong alkali. Hot solution used to dissolve shellac from some mounted work.
Read More2011-6-27 Small deposits of titaniferous iron ore in serpentine were mined for iron before 1900, but the titanium content troubled furnace operators. Ore bodies are similar in occurrence to chromite deposits; they are massive or disseminated and are found near the edges of serpentine intrusive rocks
Read More2019-6-25 The first step in extracting rhodium from the ore is precipitating precious metals such as gold, silver, palladium, and platinum. The remaining ore is treated with sodium bisulfate NaHSO 4 and melted, resulting in rhodium (III) sulfate, Rh 2 (SO 4) 3.
Read More2014-7-18 It is the dominant oxide in ordinary chondrites. Often found as small, black and opaque euhedral and subhedral grains in chondrules. Ilmenite FeTiO 3 A black, opaque, slightly magnetic mineral; the principal ore of titanium. Occurs as a common accessory mineral in terrestrial igneous rocks, achondrites, lunar mare basalts and martian basalts. 2

Weathering of rocks, both chemical weathering and mechanical weathering contribute to the formation of sedimentary rocks. Rocks that have undergone weathering will usually be carried away by water or other transport media so that they settle somewhere.
