Mr. Ukey provides administrative support to our office and is involved in software sales. He is the first contact for software sales.
The Fifth International Itasca Symposium will be held at the University of Vienna (Austria). The Symposium will features the application of Itasca software for solving engineering and scientific challenges in geomechanics, hydrogeology, microseismicity, and more.
Dr. Aglawe is a mining engineer with experience in rock mechanics (hard and soft rock) and in application of advanced numerical modeling for mining and civil projects. He has been involved in the development of models for tunnels, caverns and dams in hydroelectric projects.
Surface waters at the site of a former Minnesota taconite mine were reported to have solute concentrations elevated with respect to water-quality standards. Waste rock and ore generated from past mining were primarily from open pit mining of the Biwabik Iron Formation (BIF). The BIF is a variably bedded iron formation composed of inter-bedded cherty and slaty iron silicate and iron carbonate rich beds. A geochemical characterization was conducted to identify potential constituents of interest (COI), facilitate understanding of mechanisms controlling their environmental behavior at the site, and guide future site activities. Primary COI were determined to be SO4, hardness (predominately from Mg), alkalinity, Fe, Mn, and Al. BIF waste rock from the Lower Slaty members appears to be the primary source for the identified COI. Mechanisms of release are primarily attributed to pyrite oxidation and subsequent neutralization by dissolution of mixed-composition (Ca-, Mg-, Fe-, Mn-bearing) siderite and ankerite.
