Innovations: Introduction to Copper: Mining & Extraction
For commercial exploitation, copper deposits generally need to be in excess of 0.5% copper, and preferably over 2%. The known reserves of higher-grade ore in the world amount to nearly 1 billion tons of copper. At the present rate of mine production, which is about 13.9 million tons (12.5 million metric tons) a year, known.
Copper production & environmental impact - GreenSpec
The US Geological Survey estimated that, as of 2013, there remained 3.5 billion metric tons of undiscovered copper resources worldwide in porphyry and sediment-hosted type deposits, two types which currently provide 80% of mined copper production. This was in addition to 2.1 billion metric tons of identified resources.
Economic Feasibility Study - Dig Into Mining
Economic Feasibility Study. Overview. In this activity, students will analyze proportional relationships and use them to solve real-world problems. Students will conduct an economic feasibility study to compare production of copper at a mine site to determine if the deposits will be profitable at a particular copper selling price.

The major components can also be combined innovatively, such as when in-situ leaching of copper is undertaken after conventional mining has rubblized ore in underground block-caving.
Copper Production in Zambia in Five Easy Steps. How it is Done !
Step 1. Ore is taken out of the ground. Holes are drilled in the ground (if it's an open-pit mine) or in the rock-face (if it's an underground mine), and explosives are placed in them to blast it open. The resulting explosions leave huge quantities of copper-bearing rock – also known as ore.
