How Are Diamonds Mined? There Are Actually 3 Different

2019. 10. 28.  Alluvial diamond mining occurs in riverbeds and beaches, where thousands of years of erosion and natural forces such as wind, rain, and water currents wash diamonds from their primary deposits in kimberlite pipes to beaches and riverbeds. Miners build walls or divert rivers to expose the diamond-bearing

Mining of a diamond-bearing kimberlite generally starts with the excavation of a pit into the kimberlite pipe. In this process, called ‘‘open-pit’’ or ‘‘open-cast’’ mining, the initially weathered ore material is removed with large hydraulic shovels and ore trucks.

Diamond Mining Methods Diamond Museum Cape Town

Marine mining involves extracting diamonds from the seabed, hundreds of meters under water. The earliest form of marine mining entailed shore diving, where a swimmer would collect diamond bearing gravel from the shallow seabed. Today has evolved to specialised ships that mine for diamonds deep out at sea.
