Limestone neutralisation of arsenic-rich effluent from a gold mine
M De Beer, EH Mathews, D Krueger, J Maree… - Mine Water and the …, 2008 - Springer
Traditionally acid mine water is neutralised with lime. Limestone is a cheaper alternative for
such applications. A case study showed that limestone can be used effectively to replace
lime for the neutralization of arsenic rich acid water. The cost of limestone treatment is 45.8%
less than that of lime. The acidity can be removed from 33.5 to 0.06 g/L (as CaCO 3). The
study also showed no significant differences in the TCLP characteristics of the resultant
sludge when water is treated with lime or with limestone. Sludge from the limestone …
