This report details the work and results of a program concerned with the collection of amphibole mineral samples from the Reserve Mining taconite mine in Babbitt, Minnesota and the preparation of highly characterized amphibole fibers from these samples. A profile of the ore body was compiled after a petrographic examination of mineral samples. Various separation and sizing techniques for the fibrous material present in the ore were investigated. Air jet milling of ground and sieved fibrous rock was used to prepare samples for biological experimentation. This material was characterized by optical microscopy, electron miscroscopy, electron diffraction, x-ray spectroscopy, x-ray diffraction, atomic absorption spectrometry, B.E.T. surface area, and benzene extraction. The fibers were found to have many properties similar to amphibole asbestos types. Vials of weighed amounts of product sample were prepared and purged with nitrogen.
