ABSTRACT and FORWARD
The treatment and recovery of metal species from hydrometallurgical solutions and wastewater solids has been and continues to be an important research topic. This presentation includes a guide to the literature with a summary discussion of the research conducted at Montana Tech in the Department of Metallurgical and Materials Engineering during the 1984-2001 period. A previous presentation (Part 1) focused on the removal of arsenic, selenium, and other species by hydrometallurgical processes and the formation of environmentally stable disposable products. This guide is available at the reference presented above.
This following presentation (Part 2) is based on the research of Master of Science graduate students (13), industrial (3) and academic colleagues (4), at the Montana College of Mineral Science and Technology (which morphed to Montana Tech , then to Montana Tech of The University of Montana , then to Montana Technological University [2019). The referenced research of each of the graduate students (13) in this presentation is gratefully acknowledged. The following summary does not include other research studies conducted in the Metallurgy/Materials Engineering Department by other teaching and research colleagues. See Appendix C for a list of the Master of Science research thesis students and their research topics highlighting their contributions to our departments’ research efforts (student theses are readily available, on-line in digital format, at the Montana Tech Library).
The referenced research discussed (and annotated) in this report was supported by the U.S. Environmental Protection Agency (EPA) over a period of ten years.
