Core & Ext. Metals: Extraction
Slide 15 of 45
Extraction of metals
Once the ores have been mined from the ground, they are crushed.
Then the metal must be extracted from the ore.
As has already been mentioned, we will restrict our studies of extraction to extraction by reduction by carbon and electrolysis.
The next question is which metals can be extracted by reduction by carbon and which by electrolysis?
Those metals that are relatively unreactive, those are less reactive than carbon are extracted by reduction by carbon, while those that are more reactive by electrolysis.
