Kimberlite Diamcor defines Primary Kimberlite Projects as any diamond project which involves the exploration for, or underground mining of, any new or existing kimberlite source, these areas being the primary source where diamonds originate from
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 Hard rock is drilled and blasted with explosives so the broken material can be removed
Pit-mining is the most common way to recover diamonds In pit mining, heavy machinery, hydraulic shovels, and trucks are used to mine diamonds from the depths of kimberlite pipes
The most commonly used form of extracting diamonds is described by the American Museum of Natural History as open pit or open cast mining To begin this extraction technique a pit is created; it is dug with steep sides to create a cone narrowing to a point that is connected by roads built into large mines The large cone is called a kimberlite pipe Material is removed in large quantities by
