Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Russia, Canada, and China are other countries where copper is mined. Pure Copper Is Rare, But Copper Ores Are Abundant As mentioned, pure copper is rare because most of it is naturally combined with other chemicals to form copper ores. The most common copper ores — there are about 15 of them mined in 40 countries— are sulfide ores.

Copper is usually mined with the open-pit mining method. It involves digging a series of stepped benches deeper and deeper into the earth over time. To remove the copper ore, miners use boring machinery to drill holes into hard rock, insert explosives into the drill holes, and blast the rock into pieces. Where Copper is Mined

Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.

Copper is Recyclable Copper is one of the few materials that can be recycled repeatedly without any loss of performance. There is also no difference in the quality of recycled copper (secondary production) and mined copper (primary production), thus they can be used interchangeably.

Lucas said, "Copper is a base mineral like Chrome and Manganese, so the cost of mining it lies within that same range. The cost of mining copper is cheaper as compared to other base minerals with specific respect to net realisation ratio of the value realized against the cost of extraction".

generalkinematicsHow is copper mined?
The Stone Hill mine (also known as the Woods mine) was discovered in 1874, and worked 1874 to 1879, and 1896 to 1899. Production was hampered by poor transportation. The ore is massive and disseminated sulfides in hornblende schist of Precambrian or Paleozoic age. Principal ore minerals are chalcopyrite and sphalerite, which occur with pyrrhotite, pyrite, and quartz. Two other copper pro…

Copper can be mined using either surface mining methods or underground mining method depending on the existence of the ore body. The ore is then pulverised to improve the homogeneity in the mined ore when being sampled as copper concentration varies considerably in the ore. The pulverised ore can be sold as it is.
