Extracts from the answers: Phytomining. The copper ions can then be leached (dissolved) from the ash by adding sulfuric acid.This produces a solution (leachate) of copper sulfate. Pure copper metal can then be extracted from this solution by electrolysis or displacement using scrap iron.. Bioleaching

What is phytomining? Phytomining uses plants to absorb metal compounds from the soil. The plants are harvested and then burned to produce ash that contains the metal compounds Higher Tier Only https://bit.ly/pmt-cc https://bit.ly/pmt-cc https://bit.ly/pmt-edu
Revision notes on 4.1.4 Bioleaching & Phytomining for the Edexcel GCSE Chemistry syllabus, written by the Chemistry experts at Save My Exams.
With the development of phytoremediation technology, "phytomining" or "agromining", a new technology that extract valuable metals (such as nickel, gold, and rare earth elements) with hyperaccumulators or crops from lean ore or metal-rich soil, has gradually attracted the attention of academic and commercial fields. It's no doubt that the conventional …
Phytomining: - In phytomining, plants are grown on land containing the metal compound that we desire. - These plants absorb the metal compound, and they concentrate it in their tissue. - …

What is phytomining? 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 …
Phytomining can be used to supplement cadmium mining, for example, but has yet to produce economically viable yields. 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 can be used to supplement cadmium ...

Bioleaching. Some bacteria can live by using the energy of the bond between sulfur and copper. This separates the metal from the ore and is called bioleaching. It has the advantage that it is very energy efficient typically using only 30% to 50 % of the traditional method. It has the disadvantage that it is very slow. Phytomining.
- Both Phytomining, and bioleaching enable us to economically extract metals from low - grade ores. ^ Important, as the Earth's resources of metal ores are limited ( scarce). - Both phytomining, and bioleaching, do not involve digging, transporting and disposing of large amounts of rock, unlike traditional mining of metal ores.
Fungal Bioleaching. Fungi used: Aspergillus niger and Penicillium simplicissimum Fungal activity: Produce organic acids like gluconic, citric, and oxalic acids from glucose or sucrose.These acids dissolve metals from ores or waste. Process: The fungi convert glucose into organic acids through enzymatic reactions in the cytosol and mitochondria. The acids then …
Keywords. Low-grade ore - An ore is a rock that contains metals or metal compounds. A low-grade ore contains a lower percentage of metal or metal compound than a high-grade ore. Phytomining - Phytomining is a method of extracting metals by growing plants in soil containing low-grade ore.. Displacement - Displacement is where a more reactive element takes the …
