This study deals with the use of plasma direct reader for simultaneous mul- tielement analysis of pyrite minerals. 100mg of sample was dissolved in nitric acid and filtered. 11 trace elements iron (mostly are volatile) in the filtrate, which were suffered from iron interference were determined after passing thro- ugh cation exchange column. Filtered residue was attacked by either method depending on demands. (1) HN03+HCl ( 3+1) was used for pure pyrite and (2) alkali fusion was used when total contents of aluminum, titanium and tin were required. The resulting solution was combined with the eluted solution of some other 17 elements retained on the column and then analyzed in a separate pro- cedure.
