Research entitled Solubility of Metals Content Bangka Tin Tailings Sand Using Inorganic Acids The sample used was tailings sand from tin mining on Bangka Island which was destroyed using several variations of inorganic acids alone, H 2 SO 4 , HNO 3 and HCl and mixed with H 2 SO 4 -HCl, H 2 SO 4 -HNO 3 , HNO 3 -HCl and H 2 SO 4 -HNO 3 -HCl. Metal content characterization was analyzed using XRF. From the results of the analysis, it was found that the average heavy metals and rare earth metals were more in HNO 3 while for a mixture of acids, namely the use of H 2 SO 4 -HNO 3 .
