Investigations on different starches as depressants for iron ore flotation
The flotation studies of hematite and quartz minerals have indicated that quartz is better floated than hematite in the presence of soluble starch with dodecylamine as the collector. The flotation of natural iron ore indicated that the maximum iron recovery can be achieved by using soluble starch as the depressant.

The Importance of pH in Flotation
This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit. An alkaline solution is also slightly caustic, this will help clean the surface of the mineral. This strengthens the bond between the collector and the surface of each mineral particle.

A Review on the Application of Starch as Depressant in Iron Ore Flotation
Out of several reagents used in iron ore reverse flotation, depressants play a crucial role in selectively making the iron oxides hydrophilic and prohibiting them from reporting to the gangue-rich froth phase. Starch is widely used as the depressant in iron ore flotation. The present paper attempts to highlight different facets of starch as an ...

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.
