Upgrading 1st tin slag’s tantalum and niobium pentoxide by sodium hydroxide quenching and nitric acid leaching

Tin smelting produces byproducts in the form of slag. In tin slag, there are two valuable oxides, namely tantalum and niobium pentoxide (TNP). This research explores the effect of HNO3 leaching on increasing 1st tin slag (1TS) TNP. To deal with the investigation, roasting at 900°C, 0.5 M NaOH quench...
