The Process Of Phytomining

GCSE CHEMISTRY Extraction of Copper Thermal

Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated.

Phytomining and Bioleaching GCSE Triple Award Revision

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. These ions are leached from the ash using sulfuric acid. Scrap iron can then be used to displace the copper from the leachate.

OverviewProcessesApplicationAdvantages and limitationsCase studiesRole of geneticsHyperaccumulators and biotic interactionsPhytoscreening

A range of processes mediated by plants or algae are tested in treating environmental problems: Phytoextraction (or phytoaccumulation or phytosequestration) exploits the ability of plants or algae to remove contaminants from soil or water into harvestable plant biomass. The roots take up substances from the soil or water and concentrate it above ground in the plant biomass Organisms that can uptake high amounts of contaminants are called hyperaccumulators. Phytoextraction can also be performed by

Bioleaching Process Mining Fundamentals

Bioleaching is performed mostly by iron and sulfide oxidizing bacteria, or acid producing fungus. Some of the types of bacteria used in this process include Leptospirillum ferrooxidans, Thiobacillus ferrooxidans, and some species of sulfolobus, acidianus, and sulfobacillus.

Advantages & Disadvantages of Phytomining Sciencing

Phytomining describes the production of a metal crop by using high-biomass plants, which are plants that produce energy or a usable resource when burned. Phytominers cultivate crops of a specific plant species with high concentrations of a desired metal, harvest the plant and deliver it to a furnace to burn and gather its bio-ore.

Phytomining of gold: A review ScienceDirect
Phytomining could also assist in the sustainable closure of mining sites. Gold can be recovered from the native plants grown during the process of revegetation at the closure sites, thus Phytomining could also assist in the sustainable closure of mining sites. Gold can be recovered from the native plants grown during the process of revegetation at the closure sites, thus generating revenue along with rehabilitation (Wilson-Corral et al., 2011). The process of phytomining uses solar energy to generate bio-ore.
