About Professor Sohn

H. Y. Sohn received his B.S. degree in 1962 from Seoul National University and his Ph.D. degree in 1970 from the University of California at Berkeley. After working as a Research Associate at the State University of New York at Buffalo and as a Research Engineer at Du Pont’s Engineering Technology Laboratory, Dr. Sohn joined the Department of Metallurgical Engineering at the University of Utah in 1974 and currently holds the ranks of Professor of Metallurgical Engineering and Adjunct Professor of Chemical and Fuels Engineering.

Dr. Sohn has co-authored two monographs, co-edited 16 books, and written some 315 papers. He has served as a member of the Board of Directors of TMS, organized many international symposia, and delivered numerous plenary and keynote lectures.

HONORS AND AWARDS

Professor Sohn’s work has been recognized through various awards, which include:

  • The James Douglas Gold Medal Award (2001)
    For leadership and outstanding contributions in research and education of nonferrous extractive metallurgy and for work related to the modeling of gas-solid reactors and the development of novel solvent extraction systems from the American Institute of Mining, Metallurgical, and Petroleum Engineers.
  • the TMS Champion H. Mathewson Gold Medal Award (1993)
    For the most notable contribution to Metallurgical Science in the 3–year period.
  • the TMS Extractive Metallurgy Lecturer Award (1990)
    In recognition as an outstanding scientific leader in the field of nonferrous extraction and processing metallurgy.
  • the TMS Extraction and Processing Science Award (1990)
    For work on the Trajectories and Distribution of Particles in a Turbulent Axisymmetric Gas Jet Injected into a Flash Furnace Shaft; 1994, for work on solution mining process; and 1999, for work on chemical vapor synthesis of ultrafine intermetallic powders.
  • The Fulbright Distinguished Lecturer (1983)
  • The Camille and Henry Dreyfus Foundation Teacher-Scholar Award (1977)
SCIENTIFIC FIELDS OF STUDY

SohnThe scientific activities of Dr. Sohn cover various fields such as non-ferrous, ferrous and nano-sized materials processing industries; various processing routes such as pyrometallurgy, hydrometallurgy, chemical vapor synthesis and processing, recycling, etc. and various investigation techniques such as experimental measurements and physical modeling and simulation (CFD etc.). Specific areas of research include:

  • Fluid-Solid Reaction Engineering with applications in the reduction of oxide and sulfide minerals, mineral leaching, oxidation of carbonaceous materials and sulfide minerals (roasting)
  • Sulfide Smelting Processing with application in flash and bath smelting - reaction kinetics, thermodynamics, computational fluid dynamic modeling, minor element behavior
  • Chemical Vapor Synthesis of Advanced Materials with application to the synthesis of fine powders of metals, inter metallic and ceramic compounds
  • Solvent Extraction Processing with application in new bottom gas injected solvent extraction processes.
  • Sulfur Dioxide Streams Treatment with application in new processes for reduction to elemental sulfur
  • Chlorination Metallurgy with application in the kinetics and process analysis of titanium mineral chlorination
  • Mathematical and computer modeling (CFD etc.) of various metallurgical processes and application to pyrometallurgical and hydrometallurgical operations.
  • Hydrogen reduction of iron ore concentrate
  • Metal hydride synthesis for hydrogen synthesis

Dr. Sohn has acquired an international reputation for computer modeling and analysis in various metal extraction fields such as flash smelting/flash converting processes as well as of the minor element behavior in nonferrous smelting. He has also worked on the analysis of a channel reactor for the continuous production of copper by the countercurrent contacting of slag and matte/metal phases with bottom gas injection through gas-shrouded Savard/Lee injectors. He has developed a novel solvent extraction process called SOHNEX, which is based on bottom gas injection without mechanical agitation. His latest research work involves the Chemical Vapor Synthesis of nano-sized metallic and other inorganic materials, including advanced inter metallic compounds, WC-Co composite powders and metal-hydride hydrogen storage materials.
