  • How Are Diamonds Mined And Extracted From the Ground

    To make mining efficient and effective, the raw rock and soil are typically not examined on site. Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds.

  • Underground Mining Methods EXCELLENCE IN MINING

    Jul 21, 20160183;32;Block caving is a large scale or bulk mining method that is highly productive, low in cost, and used primarily on massive deposits that must be mined underground. It is most applicable to weak or moderately strong ore bodies that readily break up when caved. Both block caving and longwall mining are widely used because of their high productivity.

    What are the main methods of mining? PDF version. There are four main mining methods underground, open surface (pit), placer, and in situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits.

    A rarely used process of mining material, In Situ or solution mining is the process of pumping a solution into the ore body, which dissolves the ore and is then extracted by a second pump. This method is used most in mining uranium deposits, with the Beverey Uranium Mine in South Australia being the nations first operating In Situ Uranium Mine.

    Mining Mining Underground mining When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the
