Abstract

AbstractA rapid and simple method for the determination of pyrite in coal, based upon a two‐step extraction of iron from coal is presented. After milling the coal in a tungsten‐carbide vessel, the non‐pyritic iron is first removed and then the pyritic iron dissolved. This is then followed by AAS analysis. Analysis of pyritic sulfur and total iron in four types of coal demonstrate the reliability of this method.
