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)

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.
About 8% by weight of cathode ray tubes is strontium oxide, which has been the major use of strontium since 1970. [3] [4] Color televisions and other devices containing color cathode ray tubes sold in the United States are required by law to use strontium in the faceplate to block X-ray emission (these X-ray emitting TVs are no longer in production).
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.
Celestine (the IMA-accepted name) [6] or celestite [1] [7] [a] is a mineral consisting of strontium sulfate (Sr S O 4).The mineral is named for its occasional delicate blue color. ...
In the Münsterland region, its arrival caused a ″gold fever″ breakout, regarding the strontianite mining. [8] One of the biggest mines, at Drensteinfurt, was named after Dr. Reichardt, the director of the Dessauer Sugar Refinery. A further place the strontian process came to be used was the Sugar Factory Rositz (in Rositz). [citation needed]
Most of the chemistry has been observed only for the first five members of the group. The chemistry of radium is not well-established due to its radioactivity; [2] thus, the presentation of its properties here is limited. The alkaline earth metals are all silver-colored and soft, and have relatively low densities, melting points, and boiling ...
