ABSTRACT
Utilisation methods of waste calcium fluoride slurry into pulver calcium fluoride and synthetic fluorspar are presented. Synthetic fluorspar could change the way the natural raw material are used in metallurgical industry. To obtain grained synthetic fluorspar calcium fluoride, slurry is calcinated in a rotary kiln at temperature 900–1100K. Grain size and compression strength is strongly depended from calcination time and temperature. Another alternative is using of the briquetting in this process. All utilisation methods were compared.
