Open-pit mining is when the layers of sand and rocks are removed that are found above the Kimberlite. Next, the ore in the pit is broken up with the help of blasting. After the ore is successfully broken, it is loaded and taken to a primary ore crusher site, where the extraction process of the diamond will begin.

Meet the 3 Different Methods. 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 …

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 …
