Minerals and Ores

The video tutorial explains that the Earth's crust is made of rocks, which contain naturally occurring minerals. Ores are rocks with a high percentage of a specific mineral, such as hematite for iron or malachite for copper. The extraction of metals from ores involves understanding their reactivity and using single displacement reactions. A demonstration of copper extraction from malachite is provided, highlighting the process and economic considerations. The video concludes with a discussion on native metals like gold and platinum, which do not form compounds due to their low reactivity.
