On the impact of grinding conditions in the flotation of semi …
1. Introduction. Grinding and flotation operations are typically studied separately in the literature, although it is well-established that the grinding environment is a determining factor on flotation performance [1], [2].Through grinding, the physical state of the solid is changed as to particle size, particle shape/morphology, grain …

Challenges in processing nickel laterite ores by flotation
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., (1961) …
