Environmental Remediation

CAMP has significant expertise and experience in mineral processing & hydrometallurgical applications. CAMP’s experience in environmental remediation includes metal recovery from associated waste (solutions and solids), soil amendment applications, solidification/stabilization, and contaminant (metal and nonmetals) removal.

CAMP has benefited greatly from its unique placement. It is located both at a University where cutting-edge research is conducted daily to address concerns related to environmental issues, as well as is situated in an area that comprises one of teh largest superfund sites in the nation. As scuh this superfund status has served to drive research and design to the outer limits, all to discover efficient, effective, and economical solutions to widely applicable problems. CAMP has both participated in this research and benefited from being able to learn from hands-on opportunities. An added effect of its unique placement, is the fact that CAMP has been able to see both what mining can do and what can be done to fix or mitigate those impacts. As such CAMP can bring a unique view to the table to design, test, and evaluate systems of all kind.

As remediation becomes a greater focus for you and your facility, remember that CAMP has the unique knowledge and expierence to provide you with state-of-the art solutions.

Arsenic,   Selenium,   Thallium,   Metals

CAMP has world recognized personnel who have demonstrated expertise in the treatment of waste and process waters for the removal of arsenic, selenium, thallium and dissolved metals and in the environmentally safe long-term disposal of products formed during the removal treatment.

Personnel include:

  • Dr. R.G. Robins, Professor Emeritus at the University of New South Wales is one of the most published authors on the subject of arsenic removal and long-term stability of arsenic-bearing products.
  • Dr. L.G. Twidwell, Professor Emeritus, has over 40 years of experience in waste water treatment. He has supervised the work of 58 graduate students, published over a hundred papers and presented many papers at professional society conferences.
  • Mr. Jay McCloskey has over 25 years of experience in treating wastewaters. He is presently the Director of CAMP and has designed and supervised the implementation of pilot and commercial arsenic treatment systems.
  • Mr. Brian Park has 27 years of experience designing, testing and implementing selenium treatment systems.

Projects have been conducted in cooperation with the Mine Waste Technology Program (MWTP), Montana Techs’ Department of Metallurgical/Materials Engineering and/or industrial clients.

Example topics include:

  • Literature reviews covering treatment possibilities for arsenic, selenium and/or thallium removal
  • Design and modeling of waste water treatment solutions
  • Pilot scale demonstrations
  • Development of custom designed calculation programs for making first-order cost estimates that are interactive so that the user can ask “what if” questions. The interactive inputs that can be varied include solution flow rates, elemental and specie solution concentrations, solution properties such as pH, ORP, temperature, and the type of reagent and the rate of additions. The calculation program then determines the solution chemistry, the mass distribution throughout the entire envisioned process, the selection and size of equipment and estimates for reagent, maintenance, power, yearly and overall capital costs as well as the return on investment for the selected inputs.
