- Extracting copper
- we extract most of our copper from copper rich ores however, there are limited resources of copper rich ores which are in danger of running out.
- Phytomining & Bio-leaching of LOW GRADE COPPER ORES
- Phytomining
- 1)plants absorb copper ions from low grade copper ores.
- 2)plants are then burned so the copper can be extracted from the ashes
- 3) the copper can then be "leached" (dissolved) from the ash by adding sulphuric acid, making a solution of copper sulphate.
- 4)the you can use iron to displace copper.

- Bio-leaching
- 1)bacteria feed on the low grade copper ores.
- 2) by biological and chemical processes we can get a solution of copper ions (called a "leachate")
- 3) we can then use iron to displace the copper
- 4) purify the copper using electrolysis.
