(such as coal or electricity) is needed to obtain copper from CuO. What is done is simply to introducesulfuric acidinto the environment of thecopper oxide; a typical reaction is CuO+H2SO4→Cu+++SO−−4+H2O, which increases entropy and is thus spontaneous. This example shows that there...
Copper oxide and sulfide minerals react with cyanides in solution, causing high leach-reagent consumption, raising processing costs and decreasing gold recovery. According to studies, a feasible solution would be to pretreat the ore to remove copper minerals prior to cyanidation. The goal of this...

-Copper does not react with hydrochloric acid. As a metal acid reaction leads to redox reaction. Copper has a higher reduction potential than hydrogen, so it does not react with mineral acids like hydrochloric acid or sulphuric acid. -Copper oxide is a metal oxide and it...
sulphuric acidquininepolarisation methodsThe effect of quinine (Q) and strychnine (S) on the corrosion of copper in sulphuric acid has been investigated using weight loss and polarisation methods. Q and S had a significant effect on the corrosion rate of copper, the maximum corrosion inhibition (...
