    Alluvial Deposits Diamonds Mining are recovered from ore in 5 stages: Stage 1 – Crushing. Once the diamond bearing ore and gravel is collected, it is transported to a primary crusher. The primary crusher is responsible for reducing the size of the ore into smaller, more manageable pieces or chucks measuring no larger than 150mm

    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
