Handbook of Flotation Reagents ScienceDirect

The reagent practice in the flotation of nickel and copper–nickel ores depends on three basic factors: mineralogy of the ore, flowsheet employed in the treatment of a specific ore, and degree of liberation. The presence of hydrophobic gangue represents a major problem in the treatment of both nickel and copper–nickel ores. For the depression of hydrophobic gangue organics, the depressants

Froth flotation Wikipedia

For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector stone (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector). The particular stone depends on the nature of the mineral to be recovered and, perhaps, the natures of those

The effect of clay minerals on the process of flotation of

Some emerging challenges include the use of nanoparticles and new rheology modifiers. Abstract. The presence of clay leads to low recoveries in the process of flotation of copper ores which is also reflected in a decrease of the concentrates grades. Due to this, the scientific interest in studying the effect and mechanisms of action of clay minerals in the flotation process has increased
