The fractional composition of the chamber product of sulfide flotation was investigated. Grain size of the product varies from 0.2 to 0.05 mm. The characteristic of mineral composition showed that forsterite content is about 53%. The amount of other silicates (pyroxenes and garnets) is more than 20%. Two morphological generations of baddeleyite have been identified, it will be necessary to take into account physical and technological properties of the generations when developing technological solutions for gravita...

Removal of potentially harmful As compounds by adsorption onto biosorbents is a cost-effective alternative to the conventional treatment methods. Peatlands can accumulate arsenic originating from both natural and anthropogenic sources [1-3]. Wetland soils and sediments are subject to frequent changes in redox conditions, driven by fluctuations in the water table and shifts in biological activity. Under oxic conditions, natural organic matter (NOM) promotes arsenic release from metal-(hydr)oxides, thereby enhancing...
