Regulating reagents used as activators increase the difference in the hydration of separate minerals, lowering the hydration of floated particles, which in turn activate their flotation. In general, the regulating reagents used as depressants have an action opposite to that of the regulators used as activators.

Froth Flotation Process - Mineral Processing & Metallurgy

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.

Flotation | Article about flotation by The Free Dictionary

The amount of reagents used in electroflotation is considerably lower, and in some cases reagents are not needed at all. The widespread use of flotation for concentrating minerals has led to the construction of various flotation machines, with large cells up to 10–30 m 3 and high productivity. A flotation machine consists of a successive ...

They are used to improve the selectivity of a flotation process. They often make it feasible to separate minerals that were initially floated together. The response of many minerals to the flotation process is often dramatically affected by pH. Flotation circuits are often operated at a pH range of 7.5 to 11.5.

Mineral Flotation Cell Exhaust System Upgrade - Chessor

from mineral processing flotation cells. A flotation cell is a reactor in which the three phases: solid, liquid, and gas, interact to separate valuable minerals that contain saleable metals, and waste minerals called gangue. In the case of mineral flotation, the solid is the ground rock particles, the liquid is water, and the gas is usually air.

Froth Flotation. Froth flotation has been used to separate discrete mineral particles since the early 1900's. The key to effective separation of the minerals depends on differences in the surface chemistry of the minerals to be separated. The process involves the separation of hydrophobic from hydrophyllic minerals.
