Tamara Diedrich PhD, PG (MN)

Tamara applies fluency in mineral reactivity, phase equilibria, material characterization, and geochemical modeling to provide key strategic support to the mining industry. Through her work, she characterizes and forecasts how chemical elements partition between mineral, aqueous, and gaseous phases to impact water quality. Outcomes are used for mine waste management planning, environmental review, water quality-related risk management, and closure planning. Experience includes assessment of the potential for metal leaching and acid rock drainage (ML ARD) to occur during weathering of mined materials and related waste products, and identification of constituent release source terms for water quality modeling. She has extensive experience in environmental geochemistry of copper, nickel, cobalt, and PGE projects.

She received a PhD in geology from Arizona State University, and was an NSF International Research Postdoctoral Fellow at Paul Sabatier University in Toulouse, France. She has published peer- reviewed manuscripts on mineral reactivity topics related to mine waste rock management, nanoparticle reactivity, mineral fiber toxicity, and carbon sequestration.

Tamara founded MineraLogic LLC in 2016 to help mining companies identify and effectively manage the potential geochemical interactions that impact the environmental footprint of projects. As Principal Geochemist, she continues to oversee the technical integrity of all MineraLogic work products.
