Extracting metal from rock

Added by Yenka on Oct 8, 2009

This model shows a technique to extract copper from its ore. The experiment involves several stages of heating the copper ore, reacting with an acid, and finally a displacement reaction in which iron displaces copper and leaves copper metal deposited on the surface of the iron lump.

This item teaches:
