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 of the cesium it uses, primarily from ...
12)—and separated from potassium and cesium by a lengthy sequence of chemical treatments. The most common process starts with the formation of a solution of mixed alkali alums from the ore minerals either by prolonged leaching with sulfuric acid or by fusion of the ore with gypsum followed by leaching with hot water. The alums are

Water-soluble ...
Thus far, little is known about the use of granitic rubidium ore for the extraction of rubidium. Herein, we examined the extractability of rubidium and potassium from granitic rubidium ore via sulfuric acid baking, reductive decomposition, and alkaline leaching. In addition, the extraction mechanism was studied by using interdisciplinary approaches based on the mineralogy and thermodynamics.
CESIUM 119 5. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL 5.1 PRODUCTION Cesium is the rarest of the naturally occurring alkali metals, ranking 40 th. in elemental abundance. Although it is widely distributed in the earth's crust, cesium is found at relatively low concentrations.
