In this study, evaluation of Kosovo-Artana Concentrator tailings with flotation and
leaching method is aimed. The minerological analysis of sample showed that
sphalerite, galena, chalcopyrite and their oxidised forms are the main ore minerals
in the sample, while pyrite, illite, quartz, calcite and gypsum are the gangue
minerals. The metal contents of the sample are 1.2% Zn, 0.75% Pb, and 0.06% Cu.
Flotation tests to produce bulk concentrate of copper-lead and lead-zinc were
unsatisfactory. The recovery of the zinc with H2SO4 leaching were conducted both
at room temperature and at elevated temperature. The effects of various parameters
such as leaching duration, concentration of H2SO4, pulp density and temperature on
the zinc metal recovery were examined. The maximum extraction of zinc was 80%
and 89% at room temperature and at 80 ° / C respectively for 120 minutes leaching
period.
