title: Determination of the elemental sulphur content of minerals and ores.
abstract: A new technique has been developed to determine trace quantities of elemental sulphur in minerals and ores. After separation from the sample by sublimation, the sulphur is determined spectrophotometrically in ethanol. Sulphide, sulphite, sulphate and thiosulphate do not interfere. The effect of the presence of xanthate or dixanthogen is discussed briefly.
