The use of calcium and magnesium hydroxides in acid mine drainage treatment
Reagent grade of calcium and magnesium hydroxides were used in this study to treat acid mine drainage (AMD) sample. AMD sample was collected from a tin tailing pond that located in Pengkalan Hulu, Perak which as pH around 2.87 ± 0.01. pH values had increased after treated with calcium hydroxide (Ca(...
