How Are Diamonds Mined?
Alluvial mining is a simple mining process that mainly occurs on beaches and riverbeds. Many years of wind, rain, water currents, and erosion carries diamond deposits downstream from their direct deposits of kimberlite to riverbeds and beaches. These alluvial deposits are often mined from old rivers. Mining alluvial deposits can …
