Read MorePhytomining 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 ...

Read More2021-5-1 What is it: Phytomining is a method of harvesting metal from the soil by growing plants with a lot of biomass in which to accumulate the ore. These are plants which can take up elements from the soil (at rates) orders of magnitude higher than normal plants. Alan Baker. These “hyperaccumulators” thrive on metals like gold, copper, and zinc.

Read More2017-3-27 Copper(II) oxide can be reduced by reaction with carbon. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable. Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below).

Read MorePhytomining. This process takes advantage of how some plants absorb metals through their roots; The plants are grown in areas known to contain metals of interest in the soil; As the plants grow the metals are taken up through the plants vascular system and become concentrated in specific parts such as their shoots and leaves; These parts of the plant are harvested, dried and burned

Read More2021-3-10 Finite reserves of copper ores are becoming scarce and new ways of extracting copper from low-grade ores include phytomining, and bioleaching. Low grade ores only contain small concentrations of copper and would not normally be considered economic to mine and process, as would waste material from processing high grade copper ores.
Read More2019-9-20 In the process of phytomining plants are grown on top of the low grade ores. The plants absorb the copper(II) ions through their roots. The plants are then harvested and burnt to produce ashes which contain the copper(II) ions, these are then reacted
Read MoreLike phytomining, bioleaching is a useful method for extracting metals from low-grade ores. This is particularly important for copper, where high-grade ores are increasingly rare. It also uses less energy than smelting. However, some of the chemicals produced in the process are harmful, and the process is relatively slow and expensive.

Read MorePhytomining provides a further green method of managing the metal content of wastewater. These approaches represent a viable means of removing toxic chemicals from the effluent produced during the process of manufacturing, and the bioremediation process, furthermore, has the potential to save metal resources from depletion.
Read More2020-12-8 The concept of phytomining is a natural extension of botanical prospecting and the study of metal biochemistry and biogeography of metal hyperaccumulator plants. Some elements may be phytoextracted to remediate soils, but the recovered biomass would have little economic value (e.g. Cd, As, etc.) and disposal of the biomass would be a cost.
