Chemical and mineralogical characteristics of zinnwaldite wastes deposited in the Cínovec area and of zinnwaldite concentrates prepared by dry magnetic dressing of the wastes were determined. A study of structure changes in sintering of zinnwaldite concentrates with a mixture consisting of CaSO4 and Ca(OH)2 (gypsum method) was carried out. The influence of sintering conditions on Li and Rb extraction from sintering products in water was described.
