how to check the tailings ore for gold concentration

May 01, 2013· Generally base metal ore tailings have low concentration of gold. Tailings with less than 1 mg/kg gold are unlikely to have sufficient gold to justify economic phytoextraction. A higher gold grade of the tailings will yield a higher gold concentration in the plant thus allows for an economic recovery of the same (Wilson-Corral et ...
