Relatively deep deposits, or those with elongated or irregular shapes are typically mined from underground with deep vertical shafts, declines (sloped tunnels) and levels (horizontal tunnels) (Figures 8.2.1 and 8.2.2). In this way it is possible to focus the mining on the orebody itself. In some cases, the near-surface part of an orebody is ...
What is Strontium. 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.
