May 17, 2005 It is also often a by-product of silver production. Sulphides, oxides and carbonates are the most important ores. Copper and coppe r alloys are some of the most versatile engineering materials available. The combination of physical properties such as strength, conductivity, corrosion resistance, machinability and ductility make copper suitable for a wide range of applications

Feb 16, 2012 The deposit looks so small compared to the rest of the mine, but keep in mind, turquoise is just a byproduct of this copper mine. Considering the fact that the Lavender Pit copper mine is 300 acres and nearly 1,000 feet deep, one realizes that this visible turquoise deposit would still make an awful lot of turquoise jewelry

Apr 09, 2010 Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised

Mar 01, 1996 Contrary to expectations, higher bicarbonate concentrations exacerbate copper corrosion rates and by-product release. In fact, as illustrated by monitoring experiences of large utilities and by laboratory data, the concentration of copper corrosion by-products in drinking water increases linearly with bicarbonate concentration at constant pH
