The Mineral Industry Research Laboratory (MIRL) was established at the University of Alaska Fairbanks by the 1963 Alaska Legislature for the purpose of conducting basic and applied research to aid in the development of Alaska’s mineral and energy resources.

MIRL’s research activities, devoted to finding, developing and utilizing Alaska’s minerals include, but are not limited to, the following study areas: Improved exploration methods, new resource development, mining in frozen ground, surface coal mining in the Arctic, mine and mill design, mineral processing engineering, use of radiotracer techniques in placer gold recovery, hydrometallurgical and electrochemical processes for heap leaching of gold ores in the Arctic and sub Arctic, coal characterization and beneficiation, coal utilization, coal-water fuel production, mineral market evaluations, and environmental concerns associated with mining and metallurgy.

The faculty and facilities of MIRL provide an important public service function to the mineral industry. Prospectors and mine operators visit the facility throughout the year to seek advice, make use of equipment, and obtain publications pertinent to their operations. As such, MIRL functions as a source of information and support to the Alaskan mining industry, providing services and advice on problems specific to the state’s mineral development. The distribution and sale of MIRL reports, is of great importance to the mining industry. These publications play a vital role in the development of Alaska’s mineral industry, and several thousand copies of MIRL reports have been sold or distributed.

Research areas of emphasis at MIRL are dictated by the areas of expertise of its faculty and industrial needs and have varied over the years. Following is a list of research areas currently emphasized:
