Bioleaching: metal solubilization by microorganisms | FEMS
Abstract. 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 ...

BIOLEACHING - BacTech
Bioleaching, given access to a ready supply of iron, either internally generated or through the addition of pyrite from external tailings, can handle much higher levels of arsenic for neutralization. Bioleaching converts the arsenic present in the tailings into ferric arsenate, which is a stable and environmentally benign end product (EPA).

Phytomining vs Phytoextraction - What's the difference
Phytomining is a see also of phytoextraction. As nouns the difference between phytomining and phytoextraction is that phytomining is the planting (and subsequent harvesting) of vegetation that selectively concentrate specific metals from the environment into their tissues, for the primary or subsidiary purpose of commercial exploitation of the extracted metal while phytoextraction is a form …
What is 'Phytomining' and 'Bioleaching'? | Yahoo Answers
Jan 05, 2012 · This is the method mostly used in phytomining. Bioleaching uses 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.
