How Are Diamonds Mined And Extracted From the Ground

In essence, it is basically the same method employed by gold diggers which involves the screening and straining of mud. In the case of artisanal mining, the extraction process takes a longer time as low tech equipment and manual labor is usually involved. Compared to alluvial mining, the post-processing is shorter and a.

Open-pit mining - Wikipedia

This is pumped to a tailings dam or settling pond, where the water is reused or evaporated. Tailings dams can be toxic due to the presence of unextracted sulfide minerals, some forms of toxic minerals in the gangue, and often cyanide which is used to treat gold ore via the cyanide leach process. If proper environmental.
