Some Metals Are Most Commonly Obtained from Metal Oxides

SOME METALS ARE MOST COMMONLY OBTAINED FROM METAL OXIDES 

High-purity copper is recovered by electrolysis. Pure copper metal deposits on the negative electrode as copper ions in solution gain electrons. The source of these copper ions is a positively charged electrode made of impure copper. 

A mixture of iron oxide ore, coke, and limestone is dropped into a blast furnace, where the iron ions in the oxide are reduced to metal atoms.

In the furnace, the limestone reacts with ore impurities—predominantly silicon compounds—to form slag, which is primarily calcium silicate
