This document describes methods for the determination of arsenic, antimony, and bismuth contents in copper concentrates and copper slag concentrates using hydride generation - atomic fluorescence spectrometry (Method 1), potassium bromate titration (Method 2), and silver diethyldithiocarbamate spectrophotometry (Method 3). This document is applicable to the determination of arsenic, antimony, and bismuth contents in copper concentrates and copper slag concentrates. The determination ranges are. in Method 1, 0.010%~1.00% for arsenic, 0.010%~1.00% (mass fraction) for antimony, and 0.010%~1.00% for bismuth; in Method 2, 0.10%~4.50% (mass fraction) for arsenic; and in Method 3, 0.010%~0.40% (mass fraction) for arsenic.
