    Abstract The aim of the study is to investigate removal of Cu, Ni, Zn, Cd and Pb in acid mine drainage (AMD) using modified oxygen releasing compounds (MORCs) of which CaO 2 is the main ingredient. When the MORCs are placed into AMDs, OH will be released gently and continuously which can neutralize H + and precipitate heavy metal ions as hydroxide/carbonates.
