title: Rapid dissolution of sulphide ore for the determination of copper.
abstract: A mixture of equal volumes of perchloric acid and phosphoric acid is an excellent solvent for sulphide ores preliminary to the determination of copper. The dissolution is rapid, no bumping occurs, and the visual adjustment of pH prior to the iodometric determination of copper is easier.
