Solubility of metals content bangka tin tailings sand using inorganic acids

Abstract

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, H2SO4, HNO3 and HCl and mixed with H2SO4-HCl, H2SO4-HNO3, HNO3-HCl and H2SO4-HNO3-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 HNO3 while for a mixture of acids, namely the use of H2SO4-HNO3.
