PHYTOMINING OF GOLD FROM EL-SUKARI MINE SOIL

Abstract

The precious metal gold can be found at high concentration in tailings dumps and waste rock piles at many mining locations around the world. Conventional technology is generally unable to economically recover this residual gold, and, as a result, the potential resource is wasted, presenting environmental risk to the wider ecosystem through particulate and dissolved metal leaching and erosion. The sunflower plant was selected have been tested and field conditions to determine their potential for use in the phytoremediation of gold . However, the increase in the market price of gold during the first decade of the 21 st century ( on 2017), and advances recorded for the gold concentration and biomass yield of a range of plant species, suggest that gold phytomining might be an economically viable technology. The present study aims at using phytomining technology to extract gold from ElSukari soil by Helianthus annuus L plant. was this achieved by adding three gnizililulos agents : ammonium thiocyanate, ammonium thiosulphate and thiourea.
