Borehole mining - Wikipedia

Borehole Mining (BHM) is a remote operated method of extraction of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jets (hydraulicking).This process can be carried-out from land surface, open pit floor, underground mine or floating platform or vessel through pre-drilled boreholes.

Mining And Mineral Processing | The Lithosphere | Siyavula

Once a suitably sized deposit of a mineral has been found, mining can begin. In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. Mining is largely divided into surface and underground mining. Minerals are often found in river beds, beach sands and other sandy areas.

Natural Sciences Grade 9 - mstworkbooks.co.za

People extract valuable minerals from the lithosphere. Rock that contains high concentrations of valuable minerals are called ore. Various methods are used to locate potential sites for mining. Ore is removed from the crust by mining, either on the surface (open pit mining) or underground (shaft mining or room and pillar mining).
