Scientific Advisory Committee of the Prime Minister. In 1991, Peter was awarded the Gold Medal by SAIMM.

In 1990, Peter was appointed professor of metallurgy and director of the Generic Mineral Processing Center in Comminution at the University of Utah. On December 19, 1995, he became a U.S. citizen, and in 1999, he was appointed chairman of the Department of Metallurgical Engineering at the University of Utah. Between 1999 and 2006, he received many additional honors. He was appointed editor-in-chief of one of the most respected journals in his field, the International Journal of Mineral Processing. In 2002, he received the Antoine M. Gaudin Award of the Society of Mining Engineers for his “seminal research in mineral liberation.” In 2003, at the zenith of his career, he was elected to the National Academy of Engineering in “recognition of the development of useful techniques to quantify mineral liberation and his leadership in Internet education of mineral processing.” That same year, he was recognized with the prestigious International Mineral Processing Douglas W. Fuerstenau Lifetime Achievement Award.

Professor King excelled in both research and education. His research on the modeling and simulation of mineral processing operations led to the highly successful MODSIM computer software system for the simulation of plant operations. In addition, his pioneering research in mineral liberation represented a quantum leap forward in the accurate, quantitative description of multiphase particles. In fact, his research in mineral liberation provided a basis for collaboration that eventually led to a state-of-the-art micro-CT laboratory in the Department of Metallurgy at the University of Utah. Subsequently, these advances were integrated into detailed comminution models for quantifying the breakage of multiphase particles in complex grinding circuits. Dr. King’s recent research was focused on the fundamental analysis of particle fracture and the aspects of this phenomenon that limit efficient energy utilization during comminution.

Professor King was truly a “distinguished teacher” in every sense, and he gave other educators in the field a model to emulate. In recognition of his contributions, he received the University of Utah Departmental Teaching Excellence Award in 1987
