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.

What role does reactivity play in the extraction of metals?

What are the characteristics of metals like gold and platinum in relation to ores?

Summarize the key ideas presented about ores and minerals.
