The objective of the research study presented in this paper was to determine, under laboratory conditions, antimony recoveries in alkaline leaching of the stibnite (Sb2S3) sample originated from Pezinok (Slovakia) mine. The leaching media used were aqueous solutions containing NaOH or Na2S+NaOH. Establishing the effect of the following parameters on alkaline leaching: NaOH and Na2S+NaOH concentration in the leaching solution, temperature of leaching and grain size of the solid phase were the
