- getting metals from rocks
- concentrated (rid of access rocky material)
- Reduction
- the reactivity scales show whether can be used with carbon
- Electrolysis
- also used to purify an extracted metal
- metals more reactive than carbon used by elecrolysis
- breaking down metals using electricity
- liquid is needed to conduct electricity
- the liquid is metal solution or molten metal oxide
- liquid is needed to conduct electricity
- displacement reaction
- reactive metal into a metal compound dissolved In water, reactive metal will replace less reactive metal in compound
- extracting copper
- bioleaching
- used bacteria to separate copper from copper sulphide the leachate( a solution produced in the process )contains copper. then copper can be filtered from leachate
- phytomyning
- involves growing plants in soil the contain copper
- plants cant used or get rid of copper so it gradually builds up in the leafs
- the plants can be harvested, dried and burned in a furnace
- plants cant used or get rid of copper so it gradually builds up in the leafs
- involves growing plants in soil the contain copper
- bioleaching
- oxygen is removed from it
- Reduction
- the reactivity scales show whether can be used with carbon
- Reduction
