Extraction of Transition Metals
Narrated lesson · press play
Namibia mines copper, manganese and uranium — and getting the pure metal out is real, applied chemistry. Learn how carbon reduces metals from their ores, how sulfuric acid leaches metals into solution, how electrolysis and reactive-metal reduction give the pure metal, the pollution that must be controlled, and why recycling matters for finite ores.
What you'll learn in this lesson
By the end you should be able to (NSSCAS Chemistry (AS Level) 3.3.2):
- Recognise that copper, manganese and uranium are produced from ores in Namibia
- Describe the reduction of metals from their ores by carbon
- Describe the use of sulfuric acid as a leaching agent for copper, manganese and uranium
- Describe the extraction of pure metals by electrolysis of leached solutions and reduction of uranium ions by magnesium
- Discuss the control of waste from metal extraction and the benefits and problems of recycling
