INTRODUCTION INCOs Copper Refinery which is located in Copper Cliff, Ontario, about two kilometers from the Smelter, was constructed in 1929-1930 by American Metals Company and INCO. The Tankhouse operation remained largely unchanged ...
The processing of copper anode slimes is an additional economic driver for copper electrorefineries, due to the fact that slimes contain precious metals such as silver, gold and platinum group metals PGMs e.g. Pt and Pd as well as base metals like copper, nickel, selenium, tellurium and impurity elements such as lead, antimony and bismuth.
Anode slime is the insoluble product deposited at the bottom of the electrorefining tank during electrorefining of copper. It generally contains Cu, Ni, Se, Te, Ag, Au, platinum group metals PGM, Pb, Ba, Fe, etc. Owing to the presence of valuable metals and metalloids in the anode slime, numerous approaches have been made by the researchers to extract them following pyro-, pyrohydro ...

Feb 09, 2017 Dor slag is secondary product of copper electrorefining anode slime treatment. The slag consists mainly of different slag formers, such as borax and silica based minerals together with soda and traces of sealing materials. However, Dor slag also contains metals present in the anode slime, such as Ag, Cu, Bi, Sb and Te.

In the foundry, extremely direct use scrap production waste from processing plants and copper cathodes are smelted in a gas-fired shaft furnace or in electric furnaces. During the vertical continuous casting process, strands with diameters ranging from 150 to 500 mm and cakes with lengths of up to 8 m are cast intermittently.
Copper Processing Plant description There are mainly three types of copper ore sulfide type copper ore, oxide type copper ore and mixed ore. Based on abundant experiences on copper mining project, Prominer supplies customized solution for different types of copper ore. General processing technologies for copper ore are summarized as below
Jan 01, 2019 Typically, the industrial copper electrolytes contain 4060 gdm3 Cu2, 130220 gdm3 H2SO4, 0.0425 gdm3 Ni2, 0.00530 gdm3 As, and have operating temperature of 5570 C. In optimal electrorefining process, the settling rate of anode slime is sufficiently high to avoid the risk of getting the slime entrapped in copper cathodes.
