1131 Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground necessitating the removal of layer upon layer of overburden and ore In many cases logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden The
Waste rock from the open pit mine is used to build the embankment structures The embankments retain the tailings slurry in a pond where solids settle and compact Water is decanted off and used in the process plant or treated before it is discharged
Uranium resources can be extracted from the ground in three ways open pit underground and insitu leach ISL Open Pit Mining Open pit mining also known as strip mining is the removal of surficial soils and uneconomic rock to get at the ore below Ore grades are normally less than 05
Copper Mining Extraction Process Flow Chart All ore in the pit is drilled and blasted and loaded into trucks and hauled for treatment if the ore is unoxidized sulfidic ore then it needs to be crushed and milled to a fine slurry then it gets past through flotation cells in a
The Coriorcco Gold Project refers to an openpit mining operation at prefeasibility stage located at about 4100 meters above sea level in the Peruvian Andes This mining project is currently owned by the company Management Environmental Solutions MESSA and is intended to begin operations before the year 2019 To have a better understanding of the
equipment which may include a mining loader shovel or excavator Loaders lift the ore or waste material onto the trucks for removal from the mine In an openpit mine loader types can include electric rope hydraulic excavators including backhoe excavators and frontend loaders also called wheel loaders Er˘celebi and K rmanl 2000
Open pit mines can be used in coal mining and they are used extensively in hard rock mining for ores such as metal ores copper gold iron aluminum and many minerals In a open pit coal mine the pit bottom would be the bottom mined coal seam elevation since it is usually feasible to extract multiple seams when surface mining coal
Chapter 23 Guide Minerals and Mining At metal mines the target ore like gold silver copper etc is often rich in sulfide minerals When the mining process exposes the sulfides to water and air together they react to form sulfuric acid This acid can dissolve other harmful metals and metalloids like arsenic from the surrounding rock
Openpit mining also known as opencast mining opencut mining and strip mining means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow The word is used to distinguish this type of mining from extractive methods that need
