Corrosion tests were carried out on several types of stainless steel to determine their suitability for use in the construction of components for digesters to be used for the leaching of Radium Hill ore concentrates. The testing was carried out under actual leaching conditions, with varied initial acid concentrations. The ore concentrates were leached both as received and after washing them to remove chloride, which was expected to affect corrosion rates materially. It was found that, in every instance, corrosion was greater in the presence of larger amounts of chloride, and that when lower initial acid concentrations were used, corrosion was very severe even when the mineral concentrate being leached contained only 0.2% chloride. It is recommended that stainless steel should not be used for the construction of the digester components. If no alternative to stainless steel can be found, then it will be necessary to wash all ore concentrates before they are processed, to remove chloride in order to protect the stainless steel from corrosion.
