The blue Cu solutions immediately changed to colorless after cementation process. Dense easily settled metals sludge was formed. Cu was the majority element for the obtained reddishbrown sludge which the remainders were Pb, Fe, Sn, Si, Ni, Cr, and O. Cu fraction in dried sludge was % (w/w) which metallic copper (Cu) and copper (I) oxide (Cu2O) were mainly detected.

 · Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractorylined furnace of either the hearth or ...

 · Cementation is an effective process that meets the requirements of process cleanliness. The performance of the cementation reaction is dictated by a number of variables. In this study, the effects of various parameters on the yields of copper‐iron cementation (wire and powder) were investigated. Statistical full factorial designs were used to produce appropriate mixture models for the .

In the recovery of copper from the leach solution by cementation process, when aluminum is used as reductant metal, copper ions are easily reduced to its metallic state due to the difference between the electrode potentials of these two metals. The standard reduction potentials of copper and aluminum are and V, respectively.
