technical NaOH for changes in mine acid quality (pH. Fe and Mn). The method carried out by active handling is by adding technical NaOH into mine acid water. The results showed that neutralization of acid mine drainage using technical NaOH 10% to pH 8. was able to reduce Fe by 18.60 - 25.42% and Mn by 31.95 - 39.27%. at a cost of Rp.327.- per meter cubic of water 1.
