Most cesium is processed from the mineral pollucite, which is found in pegmatites. Pollucite mining is a very small scale and selective process. The United States has low-grade deposits of cesium ore in South Dakota and Maine, which are currently not economical to mine. As a result, the U.S. imports 100% of the cesium

US4597955A - Process for recovering cesium from cesium ore ...

Cesium is recovered from a cesium-bearing mineral such as pollucite by roasting with an alkaline flux to convert the cesium to a soluble salt, extracting the cesium salt with water, and separating the cesium solution from the residual solids. Water-soluble permanganate is then added to the cesium solution to selectively precipitate cesium permanganate, giving other soluble metal compounds in ...

reactivity, cesium is classed as a hazardous material and must be stored and transported in isolation from possible reactants. It is a relatively uncommon element that can be mined in only a few places in the world. The world’s largest deposit of pollucite, which is the principal ore of cesium, is in a zoned pegmatite at Bernic Lake, Canada, and

Mineral-Deposit Model for Lithium-Cesium-Tantalum

tourmaline, and apatite. The principal lithium ore minerals are spodumene, petalite, and lepidolite; cesium mostly comes from pollucite; and tantalum mostly comes from columbite-tantalite. Tin ore as cassiterite and beryllium ore as beryl also occur in LCT pegmatites, as do a number of gemstones and high-value museum specimens of rare minerals.

Caesium - Wikipedia

Caesium (IUPAC spelling) (also spelled cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium.

It's Elemental - The Element Cesium

Obtaining pure cesium is difficult since cesium ores are frequently contaminated with rubidium, an element that is chemically similar to cesium. To obtain pure cesium, cesium and rubidium ores are crushed and heated with sodium metal to 650°C, forming an alloy that can then be separated with a process known as fractional distillation.

Cesium's main commercial source is pollucite ore; however, it is also found in beryl, avogadrite, pezzottaite, and londonite. Cesium was discovered by Robert Bunsen and Gustav Kirchhoff in 1860 and first isolated by Carl Setterberg in 1882. In its elemental form, cesium has a silvery gold appearance.

Tanco Mine - Wikipedia

History. The pegmatite ore body now mined by the Tanco Mine was discovered in the late 1920s and the first mining started in 1929. Several times the mine was closed, reopened and closed, until in 1969 when it was reopened as a tantalum mine. Cabot Corporation bought the mine in 1993, and began the production of caesium brine from pollucite in 1996. Tanco Mine was purchased by Sinomine ...
