Copper concentrators typically treat up to 100 000 t of ore per day. They are loed directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of 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.
Copper (II) nitrate appears blue to the eye. This is because red light is absorbed and blue light is transmitted (Table 1). The amount of red light absorbed is directly proportional to the concentration of the copper (II) ions in the solution as defined by Beer''s Law. In this experiment we will measure the absorbance of several copper (II ...

· The copper mineralization is divided into two main components a low grade primary sulfide component, and high grade supergene zone, where the primary sulfide ore has been enriched by the leaching of copper from above, and it''s redeposition over the primary sulfide ore creating a second layer of copper mineralization on top of the primary mineralization.
The concentration of a mineral in the ore body ( % or g/t) 2% copper and gram per tonne gold: Strike Length: The length in which the mineralization is found in the ore body (horizontally) 500 meters: Depth: The depth in which the mineralization is found in the ore body (vertically) 200 meters: Width

copper electrowinning tank house and ancillary equipment calls for both understanding of the key fundamental controlling mechanisms and the practical requirements to optimize cost, schedule and product quality. For direct or post solvent extraction copper electrowinning design, key theoretical considerations include current density and
