Experimental Study on Gravity and Magnetic Separation Process for Coastal Placer in Mozambique

To exploit the titanium resource in a coastal placer of Mozambique with TiO₂ content of 3.33%, an experiment on processing technique consisting of gravity separation and magnetic separation was carried out. The conditioned pulp of the run-of-mine ore is imported into a spiral chute for gravity separation including one roughing and one cleaning processes. Then, the concentrate of gravity separation is treated with a low-intensity magnetic separation process, and its tailings are treated by a high-intensity magnetic separation process. Finally, a titanium concentrate with TiO₂ grade and recovery as 39.15% and 74.63%, respectively, can be obtained. This practice provides data and technical support for the subsequent processing of this resource.
