phytomining and bioleaching facts

What is Bioleaching? (with pictures)

Bioleaching is the use of 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 to …

Bioleaching Process

Bioleaching Process - Mining Fundamentals. 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 ...

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

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.

Producing Copper Nature''s Way: Bioleaching

Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.

Phytomining and Bioleaching

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.

Recycling of Metals | MATSE 81: Materials In Today''s World

Copper is also recycled. Once again this is a more energy efficient process than the extraction from its ore as well the copper ore supply on earth is being depleted at a very fast rate. As a result other methods for the extraction of copper such as phytomining and bioleaching are being used instead. Silver and gold from jewelry are also recycled.

Phytomining

Phytomining is the production of a `crop'' of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced.

Phytomining

Phytomining is a ''green'' technology that should appeal to the conservation movement as an alternative to opencast mining of low-grade ores. Currently, phytomining has only limited potential application (see our 2015 article below). However, he economic viability of phytomining improves as the price of metals increases.
