The Effectiveness Study on CaO Lime Dose and Operation Time Variation and Its Influence on ACID Mine Drainage Treatment
Neny Rochyani, Eddy Ibrahim, M. Faizal, and Ngudiantoro
Abstract—The use of CaO lime in an effort to neutralized the
mine water is common practice in many areas, especially mine
coal mines due to the availability of raw materials that are
relatively inexpensive and lime in order to raise the pH
capabilities has proven effective. In the mud settling ponds on
east Pit 3 West Bangko coal mine, neutralizing the mine water
is done by using calcium oxide with a predetermined dose
however its has not been measured and analyzed with the
appropriate ratio of lime dose that most effective considering
operating time to determine the effective activity of lime. This
research was conducted to compare various dose of lime and
operation time variations in the channel of mud sttling pond so
as to provide the information that is most effective conditions
for calcification. According to the results of laboratory
experiments, it is known that the best pH is the ratio of lime
dose of 0.8 g / l to 50 minutes operating time which gained the
highest pH at 7.35. while the results of the measurement of the
influence between variables is known that there is a significant
relationship between the ratio of lime dose and time of
operation to pH is about 89% and 93% and a positive
relationship between the increaseoin the ratio of lime dose on
pH and time of operations with the increase of pH .
Index Terms—Mine water, the ratio of lime dose, mud settling ponds.
