About Rutile Ore. Rutile is one of the main minerals containing titanium. It is brittle, with a hardness of 6-6.5 and a density of 4.2-4.3g/cm3. Those rich in iron, niobium, and tantalum will increase in density, and the higher ones can reach more than 5.5g/cm3. It can be dissolved in hot phosphoric acid.

Cassiterite (SnO 2) is an abundant tin mineral of economic importance. In general, the flowsheet for cassiterite beneficiation includes a combination of gravity and flotation units (Angadi et al., 2015). Gravity separation is an age-old approach used in mineral processing plants because of its low cost and environmental friendliness.
