Bioleaching & Phytomining | Edexcel GCSE Chemistry ...

Phytomining. This process takes advantage of how some plants absorb metals through their roots; The plants are grown in areas known to contain metals of interest in the soil; As the plants grow the metals are taken up through the plants vascular system and become concentrated in specific parts such as their shoots and leaves; These parts of the plant are harvested, dried and burned

Phytomining & Bioleaching By Lucy Patterson (Sophie''s …

2018-7-20 · 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.

Bioleaching: metal solubilization by microorganisms ...

Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates.Non-sulfide ores and minerals can be treated by heterotrophic ...

Evaluate the Use of Phytomining and Bioleaching in Metal ...

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 relatively slow and expensive. ...
