Development of kaolin production, reserves and processing in the Czech Republic in 1999–2015

Popis výsledku v původním jazyce

This paper aims to characterize and interpret the trends in reserves, resources, and in the mine production of crude kaolin and output of beneficiated kaolin between 1999 and 2015 in the Czech Republic. With nearly 1.2 billion tonnes of total resources, kaolin belongs to the key industrial minerals of the Czech Republic. With an annual output of about 3 to 4 million tonnes of crude kaolin and of around 0.6 million tonnes of beneficiated kaolin, the Czech Republic ranks among the top European and world kaolin producers. Mine production of crude kaolin has been relatively stable since 1997, while the output of beneficiated kaolin has been increasing gradually during the same period. The increased production and yield of beneficiated kaolin resulted from the use of progressive methods in kaolin processing, primarily high gradient magnetic separation. The positive growth trend was not a reflection of the stability of the extractive sector and domestic industry, but it was the result of a pro-export orientation. The amount and share of exports are continuously increasing and constitute 80% of the entire kaolin production sector at the present time. The only exception occurred in 2005–2008, when exports declined by one-half as a result of the government´s export restrictions. The results of analyses were not optimistic for the Czech economy and indicated a sharp downturn in the domestic mining industry. Moreover, a similar situation exists in the case of other essential industrial minerals such as feldspar, clays, and silica sand.
