How Diamonds Are Mined RockHer
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. Some alluvial deposits are from long-ago rivers. Mining alluvial deposits can be as simple as panning
THE PROSPECTING AND EVALUATION OF ALLUVIAL
2010年12月7日 Once an alluvial diamond project has been selected, the mineral resource/reserve present on the property has to be determined before it's economic potential can be estimated. Prospecting does not convert a small, low grade deposit into a commercial mine, it simply determines what the resource is and where it lies on the
Geophysical techniques touted as ideal for alluvial
