| Description
| - This article is focused on the secondary products of the sulphide oxidation processes in the environment of mine wastes created during Sb ore mining (Dúbrava and Poproč deposits, Slovakia). Mine wastes represented mainly by contaminated soils and tailings contains up to 15 700 ppm of Sb, up to 6 800 ppm of As and up to 14.14 wt. % of Fe. The tailings at Dúbrava are circumneutral (pH 7–8), richer in Sb than As and rich in carbonates. The tailings at Poproč are acidic (pH 3–5), the Sb/As ratio is usually close to 1, carbonates are missing, and the tailings have elevated Pb contents. The most common sulphide at both sites was pyrite (FeS2), less frequently stibnite (Sb2S3) and arsenopyrite (FeAsS); minor berthierite (FeSb2S4) was found only at Poproč. At both sites, sandy layers of the tailings contain the weathering products; the clayey portions are sterile. The most frequent secondary phases in the Dúbrava impoundments are oxidation rims on pyrite and arsenopyrite, with relics of the primary sulphides commonly preserved. At Poproč, the primary sulphides were completely oxidized and decomposed. Secondary oxides with no relics of primary sulphides are the most abundant Sb- and As-bearing phases in the heavy fraction of the tailings from Poproč. sulphides, oxidation, mine wastes, Sb, As
