Bioleaching is more costeffective than smelting processes. Some Bioleaching offers a different way to extract valuable metals from lowgrade ores that have already been processed. The Commercial Process. Commercial metal extraction is a quicker process that can be optimized through humidity, potential hydrogen (pH), temperature, and chemical

Phytomining (Higher Tier only) Plants absorb metal ions through their roots in a process called Phytomining . It removes toxic metals from contaminated soil around old mines for example.
Bioleaching. Some bacteria can live by using the energy of the bond between sulfur and copper. This separates the metal from the ore and is called bioleaching. It has the advantage that it is very energy efficient typically using only 30% to 50 % of the traditional method. It has the disadvantage that it is very slow. Phytomining.
Another way of using phytomining is to remove toxic metals from contaminated ground. If we grow hyperaccumulators on contaminated ground, they will remove the toxic substances from the soil, making it safe to use again. Bioleaching uses bacteria, rather than plants, to remove metals from compounds. Some bacteria can extract energy from the chemical bonds in sulfate compounds, such as copper
BBC GCSE Bitesize: The future of copper Phytomining, bioleaching and scrap iron. Some plants absorb copper compounds through their roots. They concentrate these compounds as a result of this.

Phytomining and BioleachingGCSE Triple Award Revision. Metal ores are a finite resource which are in limited methods of copper extraction exploit waste ores and low grade ores.; Phytomining involves growing plants on top of low grade plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions are leached from the ash using
Bioleaching Certain bacteria can break down lowgrade ores to produce an acidic solution containing copper ions. The solution is called a leachate and the process is called bioleaching .
Compare the processes of phytomining and bioleaching. [3 marks] This question has been written by a Bitesize consultant as a suggestion to the type of question that may appear in an exam paper.
Phytomining and Bioleaching. Metal ores are a finite resource which are in limited supply. New methods of copper extraction exploit waste ores and low grade ores. Phytomining involves growing plants on top of low grade ores. The plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions. These ions are leached from the ash using sulfuric acid.
