Waste Rock

The surrounding rock of ore body and clasp stone with no industrial value produced in the process of mining is collectively referred to as mine waste rock. For pit mining, it is the rock separated by tunnel excavation and mining exploding that can not be used as ore. For open pit mines, it is the surrounding rock or clasp stone peeled off from the mineral deposit. Generally, pit mining (underground mining) will produce 2-3 tons waste rock when take 1 ton ore, and open pit mining will peel off 6-8 tons waste rock when take 1 ton ore. Mine waste rock can be used to produce sand aggregate, concrete fine aggregate, as filler, extract iron, copper and other metals.
