3.3 Extracting metals: Displacement reaction metal issues

The displacement reaction leaves us with copper sitting at the bottom of the solution and magnesium sulphate. Copper is also commonly displaced by putting scrap iron into the copper sulphate solution. If we put a less reactive metal into the solution (e.g. gold), then nothing would happen because copper is more reactive than gold. We would still have a copper sulphate solution and gold sitting ...

What is Bioleaching? (with pictures)

About 20 percent of the world's extracted copper comes from bioleaching. Bioleaching is the use of bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded. As an alternative to smelting or roasting, miners use bioleaching when there are lower concentrations of metal in ore and they need an efficient, environmentally responsible method to extract it.

Extraction of Metals Good Science

Metals with an intermediate reactivity, such as iron and zinc, are chemically extracted from minerals by a process known as carbon reduction. Carbon reduction is a type of redox reaction, where carbon is used to displace a metal from a compound.
