Abstract: A sample (0.01-2 g) was ground with 20 mL water in a micronizing mill using sintered corundum rods. After dilution with water to 100 ml, the slurries were sonicated for 10 min and analyzed by FIA ICP-MS (Dickinson et al., BHP Research, Central Research Laboratories, 1990, CRL/S/18/90). The background noise was reduced by increasing grinding time, e.g., the peak area RSD for Cu in pyrite was reduced from 17% to 3% by increasing grinding time from 15 to 30 min. Sphalerite, pyrite, haematite, pyrrhotite, goethite and two types of coal slurries containing 2-176 mg/l Fe had the same linear calibration graph of Fe content vs. peak area; results were not affected by the slurry density or mineral hardness or density. The determination of Zn in ZnO, ZnS, sphalerite, pyrite and pyrrhotite was also unaffected by slurry mineralogy.
