摘要
This paper provides a with mineralogical and chemical study of a mineral dust at the locality Ni n芍 Slan芍. The source of the mineral dust in the mining and processing of metasomatic siderite. As revealed by the X-ray, chemical analyses and the SEM studies, the major constinuents are represented by siderite (FeCO3), wustite (FeO), hematite (汐-Fe2O3), maghemite (污-Fe2O3) and magnetite (Fe2+Fe3+2O4). Proportions of all mineral phases were quantified. There are no evidences of dust particles and chemical components whose concetrations exceed the allowed hygienic norms.
