Mineral beneficiation is a process by which valuable constituents of an ore are concentrated by means of a physical separation process. As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification processes. The most common mineral beneficiation processes include: …

2–3 tons of waste rock is removed for each ton of ore. Underground mining generally creates less waste rock than surface mining; the waste rock is either moved to the surface or used to fill in areas of the mine no longer in use. Piles of waste rock are usually deposited close to the mine. These piles can cover hundreds to thousands of acres ...

The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
