    Bentonite Quality - The Effect Of Water Chemistry And Antifreeze Agents On Bentonite Binding Characteristics
    (University of Minnesota Duluth, 2000-10-17) Engesser, John
    The primary objective of the project was to determine what test or tests best predict pre-fired pellet binding characteristics of bentonite clay. A secondary objective was to determine which antifreeze chemicals have detrimental affects on pre-fired pellet quality and which antifreeze chemicals have no affect and/or positive affects on pre-fired pellet quality.

    Bentonite Survey
    (University of Minnesota Duluth, 1999-10) Bleifuss, Rodney L
    The objective of this study was to examine the mineralogical characteristics of the various bentonites in greater detail to determine if subtle differences in the mineralogy could be related to the chemical analyzes and physical test data and perhaps explain the anomalous plant performances reported. The study was based on field samples collected from four of the bentonite companies operating in Wyoming and on representative bentonite samples provided by the taconite plants operating in Minnesota. Chemical and physical tests were run on all of the samples. X-ray diffi-action .patterns obtained from the bentonite samples under different conditions: "as received", minus 2 micron-air dried, minus 2 micron-w/glycol, and minus 2 micron after heat treatment at 250°C.
