Cassiterite (tin oxide - SnO2) is the most important tin ore. In cassiterite, Sn can be substituted by other metals such as titanium (Ti), niobium (Nb), tantalum (Ta), indium (In) and tungsten (W), which can complicate ore treatment, although some of these metals can be extracted as by-products. SXFive EPMA analysis provides detailed mineral chemistry and trace element distribution, necessary for the knowledge of ore formation, but also requested in the exploration phase for assessing ore treatment feasibility and after the exploitation phase for tailings disposal.
