Abstract

Mineralogical analyses of carbonates in depyritized tailings and pyrite concentrate (from the depyritization of the tailings) were completed as part of the tailings characterization for the Crandon Project, a massive sulfide deposit in northeastern Wisconsin. The mineralogical study was designed to determine the proportion of calcium and magnesium carbonates and, therefore, the effective buffering capacity of carbonates in the tailings. The depyritized tailings are net acid consuming and will be stored in a surface tailings-management area. The pyrite concentrate is net acid ...
