Surface Characterization of Iron Bearing and Matrix Minerals
EMSL Project ID
1727
Abstract
Using Atomic Force Microscopy, the surfaces of various iron bearing and matrix minerals will be examined to determine the topography and degree of roughness. Images will be collected of the following minerals: hematite, muscovite, biotite, ferrihydrite, goethite, quartz, and feldspar. These impages will be obtained using Contact Mode in a dry ambient environment. Using Scanning Electron Microscopy, minerals that do not have flat surfaces and are, therefore, not amenable to characterization using AFM will be examined. Environmental SEM may be employed to characterize the surface of a high and low iron smectite slurry. Once the surface characterization has been accomplished, these minerals will be used in a subsequent research project investigating the precipitation of sulfides onto mineral surfaces by sulfate-reducing bacteria.
