Lime products play a key role in the mining and extraction of non ferrous metals, including aluminum, copper, gold, nickel, cobalt, uranium, titanium and lithium Lime is also important for the pyrometallurgical refining and smelting of several non ferrous metals In addition, lime products are used in effluent and tailings treatment, and in settling, dewatering, filtration, environmental

Only then are the copper minerals broken free of the rest of the rock to be separated by flotation Concentrating The slurry of water and pulverized ore is mixed with milk of lime to raise the pH and small amounts of special reagents: a frother to make bubbles, and a collector chemical that causes the copper minerals to stick to those bubbles

From its original home buried underground in a mine to its use in a finished product such as wire or pipe, copper passes through a number of stages When it is recycled it

2 2 Industrial wastewater sources Industrial wastewater streams containing heavy metals are produced from different industries Electroplating and metal surface treatment processes generate significant quantities of wastewaters containing heavy metals such as cadmium, zinc, lead, chromium, nickel, copper, vanadium, platinum, silver, and titanium from a variety of applications

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper

Copper or bronze wire then became a very important product, being vital for the weaving industry The use of copper for sheathing the hulls of wooden boats was developed initially to prevent attacks on the timbers in subtropical waters by the teredo worm but it was subsequently found that copper clad hulls also resist marine biofouling
