title: Determination of FeS(2) in Venezuelan laterites after a sulphurization process.
abstract: A technique is presented for determination of FeS(2) in Venezuelan laterites after a sulphurization process. The determination is based on a reaction with water followed by a turbidimetric determination of sulphate ions in solution. The effect of the reaction time and of the particle size is investigated. Data are given showing the precision to be better than 3%, and the accuracy was studied by preparation of a series of synthetic samples of FeS(2), FeS and Venezuelan laterite.
