The density of a coltan bearing ore is dictated by the tantalum grade and is generally between 5.3 and 7.8 g/cm 3 (Mirji et al., 2016). However, when the tantalum content is low, other minerals being present, such as cassiterite and wolframite could possess densities close to that of colombo-tantalite.
