Description. Strontium (Sr) is the 15th most abundant element in the earth's crust. Only two minerals, however—celestite and strontianite—contain strontium in sufficient quantities to make recovery practical, and these minerals are found predominantly in sedimentary rocks. Strontium is a silvery-yellow, metallic element.

Strontium is a silvery-yellow, metallic element. Strontium belongs to a group of elements known as the alkali earth metals. Like other alkali metals, it is chemically active and will react with both air and water. Strontium Mining Only two minerals, celestite and strontianite, contain strontium in sufficient quantities to make recovery practical.

In general, the rarer the ore, the higher its volume per unit (e.g. one unit of Veldspar has a volume of 0.1 m 3, whereas one unit of Arkonor has a volume of 16 m 3). Since mining lasers mine a given volume of ore per minute, it takes longer to mine the rarer ore types. Additionally, each ore reprocesses into a different set of minerals.

Virtually all strontium compounds are processed from celestite. Because celestite commonly occurs with barium and calcium minerals with similar properties — making the separation process difficult — most strontium compound producers require raw celestite to contain at least 90 percent strontium sulfate.
