Abstract

The paper deals with the applicability and comparison of potential international methods available for the determination of the acid production and neutralization potential in sulphidic waste. A driver for such work is the mining waste directive and recently started standardization work under CEN/TC 292 Characterization of waste. A method for the determination of net neutralization potential in extractive waste is to be standardized. Here the results from two different methods for the determination of neutralization potential for five extractive waste samples are shown. Apparently the results gained with different tests even within same pH-range can differ markedly from each other.
