Polyhalite
Polyhalite is an evaporite mineral, a hydrated sulfate of potassium, calcium and magnesium with formula: . Polyhalite crystallizes in the triclinic system, although crystals are very rare. The normal habit is massive to fibrous. It is typically colorless, white to gray, although it may be brick red due to iron oxide inclusions. It has a Mohs hardness of 3.5 and a specific gravity of 2.8. It occurs in sedimentary marine evaporites and is a major potassium ore mineral in the Carlsbad deposits of New Mexico. It is also present as a 2–3% contaminant of Himalayan salt. Polyhalite was first described in 1818 for specimens from its type locality in Salzburg, Austria. The name comes from the German ''Polyhalit'', which comes from the Ancient Greek words (''polys'') and ' (''hals''), which mean "many" and "salt", and the German ending ''-it'' (which comes from the Latin ending -ites, which originally also came from Greek), which is used like the English ending ''-ite'' to form the nam ...

Woodsmith Mine
Woodsmith Mine is a deep potash and polyhalite mine located near to the hamlet of Sneatonthorpe, Whitby in North Yorkshire, England. The venture was started by York Potash Ltd, which became a subsidiary of Sirius Minerals plc whose primary focus is the development of the polyhalite project. The project will mine the world's largest deposit of polyhalite – a naturally occurring mineral. Because the project would require mining to be undertaken in the North York Moors National Park, many objections were raised to the mine and the proposed conveyor that would be installed to transport the raw material offsite to a plant on Teesside away. The mine is expected to have a life of 100 years and has been labelled the biggest mining project in Britain for decades; its twin shafts will be the deepest commercial mineshafts in Britain. The project is expected to generate over £100 billion for the UK economy over a period of 50 years. Once it is functioning it will be the deepest min ...

Sirius Minerals
Sirius Minerals plc was a fertilizer development company based in the United Kingdom. It was listed on the London Stock Exchange until it was acquired by Anglo American in March 2020. History Founded in 2003, the company initially focused on exploring the potential for potash mining in North Dakota. However, after abandoning attempts at overseas exploration in February 2012 and following approval from the North York Moors National Park Authority in June 2015, the then AIM-listed company stated that it would seek financing in order to begin construction at the Woodsmith Mine in North Yorkshire. It was admitted to the main market in April 2017. In September 2019 the Woodsmith Mine project was in doubt when the company shelved a £400 million junk bond sale, citing a lack of government support and Brexit uncertainty. In November 2019 the company announced that it was in talks with potential investors to raise $600 million needed to fund the first phase of the development. In J ...

Potassium
Potassium is the chemical element with the symbol K (from Neo-Latin ''kalium'') and atomic number19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, that is easily removed to create an ion with a positive charge – a cation, that combines with anions to form salts. Potassium in nature occurs only in ionic salts. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac- colored flame. It is found dissolved in sea water (which is 0.04% potassium by weight), and occurs in many minerals such as orthoclase, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evaporite
An evaporite () is a water-soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution. There are two types of evaporite deposits: marine, which can also be described as ocean deposits, and non-marine, which are found in standing bodies of water such as lakes. Evaporites are considered sedimentary rocks and are formed by chemical sediments. Formation of evaporite rocks Although all water bodies on the surface and in aquifers contain dissolved salts, the water must evaporate into the atmosphere for the minerals to precipitate. For this to happen, the water body must enter a restricted environment where water input into this environment remains below the net rate of evaporation. This is usually an arid environment with a small basin fed by a limited input of water. When evaporation occurs, the remaining water is enriched in salts, and they precipitate when the water becomes supersaturated. Evaporite depositi ...

Syngenite
Syngenite is an uncommon potassium calcium sulfate mineral with formula K2Ca(SO4)2·H2O. It forms as prismatic monoclinic crystals and as encrustations. Discovery and occurrence It was first described in 1872 for an occurrence as Druse (geology), druse on halite in the Kalusa Salt deposit, Ivanovo-Frankovsk Oblast', Ukraine. The name is from Greek 'συγγενής' (''related'') due to its chemical similarity to polyhalite. It occurs in marine evaporite deposits as a Diagenesis, diagenetic phase. It also forms as a volcanic sublimate, as Vein (geology), vein fillings in geothermal fields and in caves where it is derived from bat guano. It occurs in association with halite and arcanite in salt deposits; and with biphosphammite, aphthitalite, monetite, whitlockite, uricite, brushite and gypsum in cave environments. It is also found in hardened cement which has relatively higher amount of potassium. Production Syngenite can be artificially produced by the action of a potassium s ...
