<Ekstratksi tin dari sumber sekunderterbukti menjadi altematifyang atraktifmelihat dari permintaan produksi timah yang tems bertumbuh. Terak timah, yangtergolong sumber sekunder, masih menyisakan timah oksida sekitar 1 sampai 3%.Literature studi menunjukkan, untuk melakukan leaching dari terak timah secaraefektif, formasi silica gel hams di cegah, oleh karenanya asam oksalat dipilih. Empatparameter leaching, konsentrasi asam oksalat, waktu, temperature, dan rasio, dipilihuntuk mengekstrak tin (sebagai target) beserta titanium, tantalum, dan niobium.Eksperimen menunjukan, bahwa parameter leaching paling optimum berada di 24jam waktu leaching, pada 50 C dan 10% rasio cairan dan solid.
ABSTRACT
Recovering tin from secondary resource proves to be an attractivealternative tin resource to help satisfy the ever-growing tin demands. Tin slag,considered as a secondary resource, still consist of tin in the form of oxidesapproximately 1 - 3%. Studies found that in order to leach tin slag effectively theformation of S,ilica gel has to be prevented, hence oxalic acid was chosen as theleaching reagentofor the study. Four leaching parameters, oxalic acid concentration,leaching time, leaching temperature and solid liquid ratio, were tested through theexperiment to extract tin as the primary metal, along with titanium, tantalum andniobium. The experiment concluded that the optimum leaching time is at 24 hourswith a temperature of 50 C at 10% solidiliqvid ratio. |
