Metal Extraction Methods

Start with ores and extraction

Begin with the mind map Getting Metals from Rocks. It introduces ores as materials that contain enough metal to make extraction worthwhile and gives bauxite as an example of an aluminium ore. Use it to connect the idea of an ore with the metal it contains.

Next, open the mind map Extraction of Metals that covers extraction principles. It describes metal oxides and metal sulphides and explains reduction as the removal of oxygen from a metal oxide. Another map with the same title covers heating with carbon, so check the content to find the one you want.

Compare methods and impacts

The flashcards on extracting metals ask how metals more reactive than carbon, such as aluminium, are extracted. They also raise the question of why electrolysis may not be financially feasible. Use the questions after the introductory maps to practice recalling the ideas without looking at your notes.

A separate Extraction of Metals mind map focuses on aluminium and electrolysis. The Extracting Metals mind map also covers quarrying, including jobs, pollution, traffic and changes to the landscape. Together, these resources offer different starting points for studying extraction methods and their impacts.

Use a quiz with the maps

After studying a map, try the Metal extraction quiz. Then return to the map and look again at any ideas you want to study further. Flashcards can provide another way to practice recall before you try the quiz again.

Keep the unit in view

Metal Extraction Methods is a section of Metals: Reactivity and Extraction in Chemistry. As you study, use the maps to connect ores and extraction methods, and the flashcards to practice the questions raised by those connections. Choose a map and follow it with a quiz when you are ready.
