It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., …

DetailsFlotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

DetailsThe Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a co-current descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.

DetailsAll these issues combine negatively for nickel flotation, leading to the need for an excessive flotation cell footprint. Conventional flotation cells are highly constrained hydrodynamically. Firstly, for a given gas flux, G, the bubble surface flux, A = 6G/d 3,2, increases as the bubble size (defined by the Sauter mean, d 3,2) decreases.
