What is 'Phytomining' and 'Bioleaching'? Yahoo Answers

Jan 05, 2012· This is the method mostly used in phytomining. Bioleaching uses bacterialanisms 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.

Bioleaching SlideShare

The Bioleaching Process The microbial oxidation process occurs at the cell membrane of the bacteria. The electrons pass into the cells and are used in biochemical processes to produce energy for the bacteria while reducing oxygen to water. The critical reaction is the oxidation of sulfide by ferric iron.
