26/03/2016Placer mining is a way of obtaining mineral and metal resources from loose river sediments. The water helps sift the valuable resources (such as gemstones or gold) from the sand, mud, and gravel in the riverbed. Placer mining occurs on a much smaller scale than other methods of surface mining.

What is Drill and Blast Mining? The drill and blast mining, as its name would suggest, is a method of mining that begins with drilling holes into rock after careful surveying and developing a plan. Next, these holes are carefully loaded with explosives. The explosives are then detonated, causing the rock to fracture and crumble.
