The mining represents one the most common human activities that fundamentally impact not only the country itself but also have adverse effects on the fauna, flora and human beings. The negative impacts also include acid mine drainage which is formed by the dissolution of products resulting from the oxidation (chemically and microbiologically mediated) of sulphide minerals, mainly pyrite or iron disulphide...
The removal of Cu(II), Zn(II), Mn(II), and Fe(II)/Fe(III) from acid mine drainage by using coal bottom ash was investigated at pH 4.2. Metal ion sorption, measured as amount of metal ion sorbed per gram of coal bottom ash (mg/g), was strongly influenced by the L/S (liquid-to-solid ratio), contact time, and equilibrium metal ion concentration. Metal ion sorption increased with increasing contact time...
