The presence of Tl in pyrite is commonly product of the substitution of Fe 3+ for Tl 3+ in the As-rich pyrite (Cook and Chryssoulis 1990), something supported by the also positive correlation between Tl and As in the carbonate ore (r = 0.94). However, the Tl enrichment related to colloform pyrite shows an apparent positive correlation with Pb ...Web
