The Bou Dahar ore deposits, with sulfide and non-sulfide ores, were discovered in 1911 and were exploited by the mining company of Guir (la Société Minière du Haut Guir) from 1924 to 1955. In 1955, the Mining and Metallurgical Company (Société Minière et métallurgique) of Peñarroya took over the exploitation of the district until 1958.

Strontium metal had a very limited part in total strontium consumption. Small amounts of strontium added to molten aluminum improve the castability of the metal, making it more suitable for casting items that had been made traditionally from steel. The addition of strontium to the melt improved the

Le strontium 90 et le césium 137 sont les deux produits de fission les plus dangereux produits dans un réacteur ou libérés suite à une explosion nucléaire. Le strontium 90 se comporte sensiblement comme le calcium et se fixe ainsi sur les os et les dents lorsque l’on consomme des aliments ou des boissons contaminés (comme le lait).

Strontium occurs commonly in nature, ranking as the 15th most abundant chemical element on Earth. Only two minerals contain sufficient strontium, however, to be used commercially to produce strontium compounds: Strontianite (strontium carbonate) has a higher strontium content, but celestite (strontium sulfate) is by far the most abundant strontium …
