Extraction of Metals
Extract silver, copper, and iron from their oxides using different methods
Extraction Methods
K, Na, Ca, Mg, AlElectrolysis
Zn, Fe, Sn, Pb, CuHeat w/ C
Hg, AgHeat alone
Pt, AuNative state
HKDSE Tip
- Reactivity vs method:The lower the reactivity of a metal, the easier it is to extract it from its ores.
- Reduction:When extracting copper and iron, carbon acts as a reducing agent and removes oxygen from the metal oxide.
