Kwarc izerski jako surowiec do produkcji mączek kwarcowych dla przemysłu ceramicznego
Abstract
IZERA QUARTZ AS MINERAL RAW MATERIAL FOR PRODUCTION OF QUARTZ FLOURS FOR CERAMIC PURPOSES
Summary
The lzera quartz deposit, situated in the vicinity of Szklarska Poręba, has been exploited on an industrial scale, since 1958. A relatively high quality of this mineral raw material, showing a low content of harmful contaminations, excited an interest of iron metallurgy, later an also of ceramic industry. In the iron metallurgy the Izera quartz is used, in an amount of some ten thousand tons a year, for production of ferrosiliceous alloys and of technically fine silicon. A broad use of the Izera quartz in the ceramic industry has been hampered by this industry mainly due to a lack of the appropriate processing technology which might ensure the production of final material, i.e. flours, characterized by a low content of iron compounds and metallic iron introduced due to the work of processing machines. The investigations, begun in 1963 at the Department of Research and Experiments of the Industry of Mineral Aggregates and Raw Materials, carried an under the leadership of the present author, demonstrate that it is possible to determine technological conditions that may lead to the production of high-quality quartz flours useful for ceramic industry. Presenting some results of these investigations the author emphasizes the possibilities related to the technology of processing and concentration, which may increase the quality of the mineral raw material of the deposit considered. In this case, the use of technological indications, being the result of the investigations under discussion, yields us the possibility of eliminating the present-day import of quartz flours completely.
