Copper. Copper is a micronutrient in plants and an important constituent, in small amounts, of the human diet. It is a naturally occurring element in the soil and it can be found as a metal or in a variety of ores. It is a constituent of many man made alloys and is used in wire and some coins.

The concentration of copper in air ranges from a few nanograms (1 nanogram equals 1/1,000,000,000 of a gram or 4/100,000,000,000 of an ounce) in a cubic meter of air (ng/m3) to about 200 ng/m3. A cubic meter (m3) is approximately 25% larger than a cubic yard. Near smelters, which process copper ore into metal, concentrations may reach 5,000 ng

These ores respond to gravity concentration of the coarser particles of copper, and the finer particles may be recovered by flotation or, as at Calumet & Hecla Conglomerate mill, the sand portion of the gravity- plant tails may be leached and the slime portion may be treated by flotation.

Copper is naturally present in the Earth’s crust, at a concentration of about 67 parts per million. While most mines operate with copper concentrations of between 0.2 and 0.8 %, some of the richest ore bodies, located in central to southern Africa, can contain 5–6% copper.

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).

Copper tailings are a finely ground waste after copper mineral has been extracted from the ores during beneficiation. Similar to CS, the use of copper tailings as a geotechnical material has also been reported in the literature, but on a relatively smaller scale (Collins and Ciesielski, 1994; Gupta and Thomas, 2013; Nitish et al., 2013; Miller

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.
