PRECIOUS METALS, FIRE ASSAYING
Hazen’s modern fire assay facility permits rapid turnaround time and a high rate of production. Standard gravimetric finish, atomic absorption (AA), or inductively coupled plasma (ICP) analysis of fire assay doré beads are used as needed. Platinum, palladium, and rhodium are also analyzed by fire assay using the gold inquart procedure and an ICP finish.
