mining beneficiation surface

Mining and beneficiation There are two types phosphate mining methods based on the depth and deposit geometry the surface strip mining method for deposit up to 100m and the underground mining method for deposit greater than 100m However surface mining such as strip mining can affect a wide area than underground mining does therefore can mineral processing vibrating screen in ore plants
