Abstract
This report describes x-ray diffraction, scanning electron microscope, and conventional mineralogical investigations to determine elemental distribution, particle shape and size, and mineral identity of the Eight Dollar Mountain, Oregon, and Pine Flats California ores. The nickel was found to be mainly associated with a cryptocrystalline geothite, while the cobalt and minor amounts of nickel are distributed in the manganese minerals. Low concentrates of hematite and trace amounts of magnetite and chromite are present in the ores. Major silicate minerals present are antigonite serpentine, chlorite, talc, and quartz. Nickel, aluminum, and chromium are incorporated in the geothite lattice. The report also includes characterization of these ores after reduction and leaching to provide information on the progress of the extraction treatments.
