title: [Identification of crystalline phases and various metal content of fibrous minerals (Polish asbestos) found in nickel ore deposits].
abstract: Nickel ore deposits near Szklary in Lower Silesia are accompanied by minerals of clearly fibrous structure ("Polish asbestos"). The pulverization process of those minerals yields particles resembling fibres. Basing on the diffractometric characteristics and absorptive spectra analysis in infrared, crystalline phases were identified in five dust samples of those minerals. The major crystalline phases were found to be: anthophyllite (samples 1, 2, 3), quartz (samples 2, 3, 5) and antigorite (samples 4 and 5). Tests on X-ray spectrometer SPARK-1 indicated that all the samples contained ferrum (1-2%), nickel (0,08-0,15%), copper (below 0,005%), in one sample the content of zinc amounted to 0.006%, in the other the content of zinc and chromium was lower than their detectability limit. Air dustiness in the nickel ore mine and nickel ore processing plant may result in serious diseases in those inhaling the dust. The pollution of air, water and soil in the mine environs cannot be neglected, either.
