Rubidium Mining | Processing Equipment | Flow Chart
Rubidium (Rb) is a very soft, silvery-white metallic element. Rubidium does not combine with other elements or ions to create minerals. Like other alkali metals, rubidium reacts violently with air and water. When exposed to air, it bursts into flame, and explodes when put in water. Its melting point is so low (103 degrees F, 40 degrees C) that ...

Strontium Mining | Processing Equipment | Flow Chart
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.

Tantalum is a hard, grayish-blue, metallic element. Tantalum Mining. Tantalum is recovered from ore minerals such as columbite and tantalite that are mined in open ...
DIAMOND MINING AND THE ENVIRONMENT FACT …
Diamond mining uses water, rather than chemicals, for extraction, but of course, water is scarce in many parts of Africa, where diamond mining companies often operate. This makes it even more important that the diamond mining process does not pollute natural water sources and that it uses as little as possible. Taking action
