Phytomining and Bioleaching - Revision Cards in GCSE Chemistry

Bioleaching is the extraction of specific metals from their ores through the use of bacteria. They do this by producing leachate solutions that contain the metal compounds. A leachate is simply the solution we get when a liquid passes through an organism.

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.

Phytomining - ScienceDirect

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. Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, opencast ...

Phytomining & Bioleaching By Lucy Patterson (Sophie's Sibling)

BIOLEACHING is very similar to phytomining, BUT there are some differences. What does it do? Bioleaching is also a method of extraction. However it extracts copper . compounds from BACTERIA. How do the compounds get there? Like some plants, some bacteria will absorb copper compounds. They then will . produce solutions called LEACHATES.

Bioleaching - Wikipedia

Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt

Bioleaching - an overview | ScienceDirect Topics

Bioleaching was used industrially for recovery of various metals from low-grade mineral resources [641]. In addition, the article published by Santhiya and Ting [525] lists the waste materials, such as fly ash, sewage sludge, spent batteries, and electronic scrap materials, as well as the fluid catalytic cracking (FCC) and hydroprocessing ...
