  • How Are Diamonds Extracted? | Bizfluent

    The most commonly used form of extracting diamonds is described by the American Museum of Natural History as open pit or open cast mining. To begin this extraction technique a pit is created; it is dug with steep sides to create a cone narrowing to a point that is connected by roads built into large mines.

  • Mineral Extraction - The Environmental Literacy Council

    Longwall mining allows for increased mineral extraction to occur, since it shears entire blocks of mineral onto a conveyor belt through the use of self-advancing, hydraulic roof supports or shields. Once the mineral is extracted, the supports move on and the roof is allowed to collapse.

  • Innovations: Introduction to Copper: Mining & Extraction

    The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

  • Extraction of Resources | Geology

    The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
