Neutralization Potential of Overburden Samples Containing Siderite

Abstract. Acid-base accounting (ABA) is a common procedure to predict the alkaline or acid-producing potential of overburdens. Neutralization potential (NP) as currently written in ABA overestimates alkalinity when siderite (FeCO3) is present in the overburden. Siderite initially yields alkalinity upon digestion, but with time.
