Who Should Attend

This one day course is intended for scientists, engineers, plant operating engineers, environmental engineers, and managers who are involved in the processing of arsenic bearing materials and its disposal in the non-ferrous metal industry. It is highly recommended not only for environmental professionals seeking a first introduction to arsenic metallurgy, but also those with prior but dated or limited experience.

Course Overview

Arsenic has been a problem associated with the extraction of non-ferrous metals and precious metals. Until 20 years ago, arsenic tri oxide from the non-ferrous industry was used as chromated copper arsenate as protection for lumber. However, with the banning of its use for domestic lumber in USA, its usage has decreased considerably. This has raised environmental concern about its safe disposal during the processing of base and precious metals. This one day interactive course will include:

  • Role and distribution of arsenic during processing of base metals and precious metals.
  • Treatment of As-containing byproduct streams for As removal.
  • Fixing of arsenic in slags; Bevill Amendment.
  • Treatment of aqueous effluents for heavy metals’ removal including arsenic.
  • Aqueous chemistry of Arsenic
  • Chemistry of Waste Water Treatment with special reference to Arsenic Removal.
  • Formation and Stability of Arsenic Compounds–Fe/As coprecipitates and Scorodite
  • Concluding Remarks.

About the Presenters

V. ”Ram” Ramachandran is a Consulting Engineer to the Non-Ferrous Metal Industry. Ram has worked in the R and D department of ASARCO for about 26 years. Ram holds a Ph.D. in Extractive Metallurgy from the Colorado School of Mines. He is a Registered Professional Engineer in the State of Arizona and a Qualified Environmental Professional with Specialization in Water Quality. Ram has been very active in the Extractive and Processing Division of TMS. He has published extensively in the area of Extractive Metallurgy including a review paper on As removal from waste streams.

George P. Demopoulos is professor of Metals and Materials Engineering at McGill University, where he is teaching and conducting research in the area of hydrometallurgy and environmental protection. One of his major research programs over the past 10 years has been the study and development of know-how and technology for the fixation of arsenic in the form of scorodite. He has to his credit some 150 refereed publications, over 40 graduate students and postdocs trained in his laboratory and is the co-inventor of 6 patents.
