Mohd Syahrir Mohd Rozi, . and Soudah Masduki, . (2009) Initial study of Acid Mine Drainage AMD potential at Mengapur copper mine using Acid Base Accounting ABA method. [Proceedings Paper]
Abstract
A few samples of sulphide rocks from Mengapur Copper Mine have been collected for the test of Acid Mine Drainage AMD prediction. The rock samples were characterised and subjected to two static tests. The samples contained 7.7 to 11.4 sulphur most of which associated with pyrite and pyrrhotite. The total calcium and magnesium oxide content of the samples ranged from 1.3 to 1.6 The Acid Production Potential APP and Neutralisation Potential NP were determined by Acid Base Accounting ABA method via two static tests. The static tests that have been used are the BC Resean::h Initial Test and Lapakko Procedure Test. The Net Neutralisation Potential values NP -APP indicated that the samples were acid producers thus have great potential for AMD to occur in the future. Using ABA values all the samples had NP:APP ratios less than 3:1 a value proposed in California for identification of acid producing wastes.
