Scaling up copper production will also encounter resistance from environmental groups as opencast mining and smelting are both highly polluting activities. Opencast mining is an eyesore and releases sulfuric acid and heavy metals into local water systems whilst smelting liberates large volumes of sulphur dioxide. With the depletion of lowcost deposits in developed countries, production and ...

· There are two main copper ore types in mining: copper oxide ores and copper sulfide ores. Both ore types can be economic, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for ~50% of copper production. Sulfide copper ores are the most profitable ores because they have high copper content, and refiners easily separate copper .
