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.

CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION …

The collector is the most important reagent used in the iron ore flotation process. The function of the collector reagent is to promote affinity between mineral particles and air bubbles by formation of a water-repellent coating on the surface of the mineral particle. Most collectors in current use are heteropolar; i.e., they contain both a polar
