Strontianite (Sr C O 3) is an important raw material for the extraction of strontium. It is a rare carbonate mineral and one of only a few strontium minerals. It is a member of the aragonite group. Aragonite group members: [2] aragonite (CaCO 3), witherite (BaCO 3), strontianite (SrCO 3), cerussite (PbCO 3)
Strontium carbonate is a white, odorless, tasteless powder.Being a carbonate, it is a weak base and therefore is reactive with acids.It is otherwise stable and safe to work with.
The mining of strontianite in Germany ended when mining of the celestine deposits in Gloucestershire started. [43] These mines supplied most of the world strontium supply from 1884 to 1941. Although the celestine deposits in the Granada basin were known for some time the large scale mining did not start before the 1950s.
