Article PDFSecondary mineralization on the mine waste of the Kukla coal mine in Oslavany
Secondary minerals on the waste tip of the Kukla coal mine in Oslavany are described. In the 2005, sulphur, gypsum and hexahydrite were collected and verified. New phases for the locality are secondary anhydrite, aragonite, hematite, calcite, konyaite and spinels. Massive hematite and spinels formed at high temperature during the burning of the mine waste. Other secondary minerals are younger and according to climatic condition repetualy recrystallize on the surface of the coal dump.
