Figure 1From: Dynamics in leachate chemistry of Cu-Au tailings in response to biochar and woodchip amendments: a column leaching studyDynamic of electrical conductivity (EC) in the leachate over six cycles of leaching. EHM, pure tailings; EHM + 20% woodchips, tailings with woodchips; EHM + 10% biochar, tailings with biochar amendment.Back to article page
