  • How Are Diamonds Mined And Extracted From the Ground

    In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor. Compared to alluvial mining, the post processing is shorter and is a less resource consuming task as diamonds are identified in situ of the work area.

    Full Answer. However, the difference is that in this method the gold is a by product of the primary material that miners mine at the site. In most cases, copper, sand and gravel are the primary materials and gold becomes a by product when miners conclude that there is enough gold to justify mining.
