Phytomining is the use of hyperaccumulating plants to extract a metal from soil with recovery of the metal from the biomass to return an economic profit. This work looks at the possible methods for recovering gold from plant material, including chemical reduction with and without solvent extraction, thermal reduction and copper electrodeposition.
The technique of finding gold called phytomining uses plants to extract particles of the precious metal from soil. Some plants have the natural ability to take up through their roots and concentrate metals such as nickel, cadmium and zinc in their leaves and shoots.
Phytomining of gold involves extracting gold from soil substrates by harvesting specially selected hyperaccumulating plants. Phytomining has potential to allow economic exploitation of low grade ores or mineralized soils that are too poor for conventional mining of metals.
of plants as a biological system for the synthesis of synthesis of gold nanoparticles using plant extract, the worldwide research progressing in this field and their applications. Synthesis of nanoparticles using plant extracts Nanoparticles synthesise can be carried out by various chemical
