Phytoextraction of gold and copper from mine tailings with

Oct 01, 2011· Anderson et al. (2005), reported a significant increase in the copper concentration of field-grown plants as a result through gold phytoextraction, and attributed the mortality of plants used to copper toxicity. Copper is an important industrial metal, and is considered the third most commonly used metal around the world.

Phytoextraction of gold and copper from mine tailings with

Highlights Gold occurs with copper in mine tailings. If gold phytomining is to be used to recover gold, the effect of copper on plant health must be considered. Both Helianthus annuus and Kalanchoe serrata accumulate gold, but show differential uptake of copper. Geochemistry, suitability of plant to climate, and uptake of metals other than gold should be considered. The potential for economic

Reports about the copper recovery using plants are abundant in the scientific literature (Almeida et al., 2008;Murakami and Ae, 2009;Wang et al., 2010).Given the general association of copper with gold in waste rock and tailings, it is important to consider the interactive effect of copper on gold phytoextraction.

Gold phytomining in arid and semiarid soils

Field trials for gold phytoextraction During 2003 the first field trial for gold phytoextraction from mine tailings was conducted using sodium cyanide and ammonium thiocyanate as chemicals to induce gold hyperaccumulation (Anderson et al. 2005). In this work Brassica juncea Czern. (Indian mustard) and Zea mays L. (maize) were used to recover gold
