Abstract

The contribution deals with recovery of useful minerals such as siderite and barite from tailings collected in settling pit nearby
Markušovce village (East Slovakia). The material form the pit was subjected to gravity pre-concentration and magnetic separation
under laboratory conditions with the aim to verify a possibility of siderite and barite concentrates preparation. A fraction of +0.2–1
mm forming a 40.56 wt% of total grain size scale of the material from the pit and containing 35.71% SiO2, 22.55% Fe2O3, 7,12%
Al2O3, 5.48% Ba, and 3.89% SO42– was tested in upgrading process. Thus, 78.18% of SiO2, and 60.41% of Al2O3 at loss 21.70%
Fe2O3 and 2.09% of Ba were removed in gravity pre-concentration. The iron concentrate with the content of 44.33% Fe2O3 at Fe
recovery of 77.29% in magnetic product was obtained. Barite pre-concentrate with the Ba content of 46.21% at Ba recovery of
91.95% in non-magnetic product was won.
