Bioleaching, or microbial ore leaching, is a process used to extract metals from their ores using bacterial micro-organisms. The bacteria feed on nutrients in the minerals, causing the metal to separate from its ore. The metals commonly extracted using this process include gold, silver, zinc, copper, lead, arsenic, antimony, nickel, molybdenum ...

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.
Phytoextraction and bioleaching (bacterial) are two relatively new methods of extracting metals that rely on biological phenomenon. Both of these methods avoid the significant environmental damage caused by the more traditional methods. They are however very slow and also do require either displacement or electrolysis to make the final product.
What two methods can be used to extract copper from a solution of copper sulfate produced by bioleaching or phytomining? Electrolysis or displacement. In the electrolysis of copper, give the half equation that shows what happens at the negative copper electrode ... AQA GCSE Chemistry : CHEMICAL CHANGES. 81 terms. asta23 PLUS. Chemistry GCSE AQA ...
Bioleaching is in general simpler and cheaper to operate and maintain than traditional processes. The bacterial leaching process is very slow compared to other methods. The process is more environmentally friendly than traditional extraction methods. Less profit is made from bioleaching which means it is less appealing to buisness men and women.
Cu2+(aq) + Fe (s) → Cu (s) + Fe2+(aq) Like phytomining, bioleaching is a useful method for extracting metals from low-grade ores. This is particularly important for copper, where high-grade ores are increasingly rare. It also uses less energy than smelting. However, some of the chemicals produced in the process are harmful, and the process is ...

Phytomining describes the production of a metal crop by using high-biomass plants, which are plants that produce energy or a usable resource when burnt. Phytominers cultivate crops of a specific plant species with high concentrations of a desired metal, harvest the plant and deliver it to a furnace to burn and gather its bio-ore.
