    how are diamonds seperated from ore waste rock. Ore and waste will be trammed at different times and tipped into two separate orepasses dedicated to ore and waste onlyThe main reason for this approach is that very limited ore dressing studies (ODS) have been completed on the kimberlite, waste rock and diamonds and therefore it is considered wise

    2018-11-12 · The heavy minerals, including diamonds, are separated from waste material based on their density differences in a dense media separation process. In this process, ore is mixed into a ferrosilicon slurry, then fed to a dense media cyclone, where the heavy minerals are separated from the waste.

    Add ferro-silicon sand to the mixture of water and ore to further separate the diamond crystals from the volcanic material. Remove the ferro-silicon with a magnet, and empty out the water. Small diamonds and a few diamond-laden chunks of heavier rock should be all that remain. Related LeafTv Articles.

  • How Are Diamonds Mined And Extracted From the

    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.
