In order to estimate the reduction current generated on the copper surface by the oxygen entering the cell, the reaction is written as O 2 +2H 2 O+4e-→ 4OH-.Thus the current is calculated to be I = 4FJ = 4 × 96500 × 0.63 × 10 −11 = 2.4 × 10 −6 A. It is worth mentioning that in fact this current represents the upper limit of oxygen reduction, since it …

The copper ores are mostly found in the north of India. The extraction of copper also involves many steps. The ore used for extraction is copper pyrites, which is crushed, concentrated and then heated in the presence of air. During heating the moisture gets expelled and the copper pyrites gets converted to ferrous sulfide and cuprous sulfide.

April 21, 2018. Every second, metals that form the components of our day-to-day electronics are thrown out. There are currently no efficient methods for recycling them, yet our need for these metals remains strong. Yale researchers have developed a solution that salvages metals at their "end-of-life" stage and allows them to be used once again.
