Abstract
Acid mine drainage is an important environmental impact of mining activities, both ore and coal mining which are oxidized with sulfide minerals. In addition to low pH, acid mine water also contains heavy metal ions such as Cu, Si, Mg, Al, Mn, Fe and others. Materials used in the processing of acid mine drainage are materials that have alkalinity such as coal fly ash has the potential to have alkalinity levels and so far has only been considered a B3 waste. In this study, fly ash is used as the main ingredients for treatment in order to meet river water quality standards is by neutralizing the pH, reducing the content of dissolved solids (TDS) and reducing the electrical conductivity (EC) of acid mine drainage using coal fly ash. Various variables used in this study; including the independent variable in the form of variations in the dose of coal fly ash (20 - 60 gr) on acid mine drainage and jar test-stirring speed (100 - 300 rpm).The dependent variables examined were pH, TDS and EC. This research conducted by the aim of studying the effect of coal fly ash on research parameters. The results obtained show that coal fly ash can increase the pH value by increasing percentage by 67,56 – 105,41%, increasing TDS value by increasing percentage by 8,49 – 202,58% and increasing EC value by increasing percentage by 11,68 – 187,23%. The affixing of coal fly ash with a dose 20 gr at a stirring speed of 300 rpm is the optimum condition with results that meet the quality standards of wastewater from coal mining activities and environmental quality standards.
