  • The diamond mining life cycle Mining for schools

    Step 1: Exploration Geologists use many methods to explore for kimberlites – the primary sources of diamonds – including satellite remote sensing, geophysics and reconnaissance sampling Any kimberlites discovered can then be drilled to establish whether or not they contain economic quantities of diamonds

  • How Are Diamonds Mined And Extracted From the Ground

    So, let us also take a look at some methods in which rough diamonds are extracted from the ground Here is a list of topics we will be covering: Diamond Pipe Mining – Open Ground/Underground Alluvial Diamond Mining – Gathering Diamonds on the Surface Offshore Marine Diamond Mining
