Innovations Introduction to Copper Mining Extraction

Commercially exploited deposits of copper ores are found in many parts of the world frequently associated with mountain building processes Deposits occur at many locations in the western cordillera of the Americas mainly in the United States and Chile and in areas of the North American plains like Michigan Ontario Quebec and Manitoba at sites associated with the Pre Cambrian shield.

Mining

Open Pit Mining Ores closer to the surface are accessed by creating an open pit and then excavating the ore below for further processing In most cases a significant amount of overburden which is a layer of rock or soil that covers the deposit must be removed.

Iron Ore Analysis Process Optimization Solutions

Decreasing ore grades of existing or new iron ore deposits require predictive solutions to efficiently sort and blend iron ore for optimal and profitable beneficiation and downstream processing Elemental and mineralogical composition as well as predictive models for the upgradability based on metallurgical parameters such as washable constituents play an important role for iron ore producers.

How Ore Deposits Are Formed

Finding new ore deposits in the Earth s crust depends on our understanding how nature forms such gigantic metal accumulations that can be exploited at reasonable economic and environmental expense Until now geologists have primarily studied these deposits using field observations and geochemical analyses but were unable to fully understand the physical processes of ore formation.

ICMM Operating mines

Surface mining involves the stripping removal of surface vegetation soil and if necessary layers of bedrock to reach buried ore deposits Common techniques for surface mining include Open pit mining and quarrying The recovery of ore from a progressively wider and deeper hole in the ground using large vehicles to haul the ore from the pit to the processing facility.
