C.* Dr. Shanthappa B.C** Abstract: Industrialization extremely demands to the uplift of nation's economy.
Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-

At the moment, Jon Dean's "green" project is looking grey. Dean, a Montana State University-Bozeman student, and his advisor, Jerry Stephens, are mixing a batch of "environmentally friendly" concrete using waste from a nearby gold mine.
They are used as pumps for feeding filter presses, reactors or autoclaves, transporting mine slurry and tailings, and for mine dewatering and refilling. Acidic ore slurry in nickel, copper and gold mines presents a special challenge.

Mining companies may sell copper in concentrate or cathode form. As mentioned above, copper concentrate is most often refined at a different location than company mine sites.
the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages. Separation of special copper ores such as those containing molybdenite or with high zinc or lead ... intermediate products (e.g., cement copper or copper(I) oxide precipitates), reverts (e.g., converter
The precipitated copper is washed and drained into settling tanks. After the cement copper settles, the clear water is decanted and recirculated for leaching. The cement copper is further drained, air-dried to 15 percent moisture on drying pads, and shipped.

Mining in Iran is underdeveloped, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014.
Cement kiln dust (CKD) is a fine-grained solid by-product generated during the cement manufacturing process and captured by the facility's air pollution control system. Because much of the CKD is unreacted raw materials, it is often returned to the production process.

Copper minerals and ore are found throughout the Earth's crust. They occur in both sedimentary and igneous rocks. The outer 10km of the crust contains 33g of copper for every tonne of rock. This is not enough to make it commercially viable to extract the rock.
These protective measures are in no way dictated by the interaction of the concrete and the copper tube. According to the Portland Cement Association the interaction of copper with both dry and wet concrete should not cause a corrosion concern.
If copper is the thoroughbred of the Arizona mineral industry, industrial minerals are surely the workhorse. The sand, gravel, and broken and splintered rock that mantle Arizona basins – collectively referred to as aggregate -- are a mineral bonanza.
When the mine closed it had produced 495,107 tons of ore, including 4,257,571 pounds of uranium oxide, 6,680,000 pounds of copper, 107,000 pounds of silver, and 3,283 pounds of vanadium oxide. The value of the uranium alone has been estimated at $40 million.
