Extracting Metals Flashcards
State the process for extracting metals?
Start with the metals ore, which is chemically combined with other impurities. Then concentrate the metal ore and carry out chemical reactions which removes the oxygen
How can the metal extracting process change?
1) if the method is cheaper
2) if the method extracts more
What happens when you react iron oxide and carbon?
You form iron and carbon dioxide because carbon is more reactive than iron as carbon strips the oxygen away from iron
If you wanted to react aluminium oxide with carbon?
Melt the ore and use electricity this process is called electrolysis- disadvantage due to how expensive it is
How do you make impure copper pure?
Use electrolysis
What are the problems with copper? (2)
1) copper rich ores are running out
2) there are environmental issues
