This project plans to study existing data from an active mine containing porphyry copper tailings, collect preliminary samples, and identify prospective laboratory techniques to evaluate factors in determining feasibility of extracting byproduct commodities."

We plan to analyze the existing data and reports from an active mine site on the composition of their mill tailings pile, and collect preliminary reconnaissance samples to identify appropriate analytical techniques that will be most useful to this study. The array of techniques considered will span standard and advanced mineralogical characterization techniques."

     "text": "Preliminary reconnaissance investigations have identified anomalous concentrations of a variety of byproduct critical minerals in mill tailings from a variety of mineral deposit types (Seal and Piatak, 2017). The viability of recovering byproduct commodities from legacy tailings will require not only knowledge of the bulk concentrations of these elements in the tailings, but also detailed understanding of their mineralogical hosts. The ability to separate minerals using techniques such as froth flotation or dissolution is mineral-specific. Although anomalous concentrations of many byproduct critical minerals have been found in a variety of mill tailings, it is unclear if recovery of these elements is economically feasible on their own merits, or if recovery can offset environmental management costs, including mine closure."
