Nickel was upgraded in two samples of saprolite and the intermediate zones by gravity separation using the Falcon concentrator. The Ni grade increased by 17% and 36% for the saprolite and intermediate samples (i.e. ore S and I), respectively.
Nickel is widely used in industrial processes and plays a crucial role in many applications. However, most of the nickel resource mainly exists as nickel oxide in laterite nickel ore with complex composition, resulting in difficulty in upgrading the nickel content using physical separation methods. In this study, high-grade ferronickel concentrates …
A number of physical separation techniques for nickel (Ni) laterites have been investigated at laboratory and pilot plant scale and reported in the open literature. These included sink–float (or dense media) separation, gravity separation, magnetic separation, electrostatic separation, (roasting) and flotation.
Thus, upgrading nickel content by gravity concentration, before the hydro metallurgical or pyro metallurgical processing, is necessitated. Application of the falcon concentrator for nickel was studied, taking into account the different types of laterite ores. ... Falconer A (2003) Gravity separation: old technique/new methods. Phys Sep Sci …
