Alternative Methods of Extracting Metals | AQA GCSE ...

Phytoextraction and bioleaching (bacterial) are two relatively new methods of extracting metals that rely on biological processes. Both of these methods avoid the significant environmental damage caused by the more traditional methods of mining. Traditional mining involves a great deal of digging, moving and disposing of large amounts of rock.

why is copper extracted from low percentage ores | …

These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable. Bioleaching and phytomining are increasingly used to extract copper from low grade ores see below. The traditional method of extraction is CopperII sulfide gives copper and sulfur dioxide during thermal decomposition.
