The Enhancement of Uranium and Thorium in Bangka Tin Slag

Several studies have indicated that consumer goods, air pollution, and by-products, residues, and waste products of natural resources exploitation contain uranium and thorium. In this research, the enhancement of these two metals resulted from the extraction process of Bangka tin slag. To deal with the enhancement of uranium and thorium, Bangka tin slag (BTS) was dissolved in hydrofluoric acid (HF), hydrochloric acid (HC1), and sodium hydroxide (NaOH). The result shows that Bangka tin slag has high contents of uranium, 3404 ppm, and thorium, 25 850 ppm, which were achieved through the dissolution of BTS-roasting-quenching-sieving (BTS-RQS) residues in HF 8 %, HC16 M, and NaOH 10 M.
