copper ores left copper metal is in demand copper is expensive now economical to extract copper from low grade ores. Metals are extracted from their ores. Many copper ores contain only 2% of copper compounds. Copper is now extracted from ores containing a low percentage of copper compounds. Suggest two reasons why.

Oct 29, 20180183;32;Typical throughputs of a large copper mine can be in excess of 5000 tph of milled ore and a microwave based treatment system would need to handle equivalent throughputs. This is at least an order of magnitude higher than any other microwave process ever built.
Following is a list of minerals that serve as copper ores in the copper mining process
For mid grade ore, about 0.25 per cent copper, extraction is projected to reach 50 per cent after two years when heap leaching tertiary crushed ore at 60176;C and pH 1.5.

Metal ores are generally oxides, sulfides, silicates, or native metals (such as native copper) that are not commonly concentrated in the Earth's crust, or noble metals (not usually forming compounds) such as gold. The ores must be processed to extract the elements of interest from the waste rock and from the ore
