Flotation Reagents

Frothers are usually added to the pulp just before its entrance into the flotation machine. The quantity of frother varies with the nature of the ore and the purity of the water. In general from .05 to .20 lbs. per ton of ore are required. Some frothers are more effective if added in small amounts at various points in the flotation machine circuit.

Copper Processing | Multotec

The slurry is transported to a flotation circuit where the copper mineral is separated from gangue. Chemical reagents (termed "collectors") are added to the slurry to connect with copper minerals, making them hydrophobic (water repellent). Air is introduced into the flotation cell allowing the formation of bubbles, which then rise to the ...
