Flotation - an overview | ScienceDirect Topics
Flotation is a technique, widely used by the mining industry, for the separation of minerals, phosphates, or coal from gangue. Coal and minerals particle size and surface hydrophobicity are two main parameters that affect three key steps in froth flotation process: particle–bubble collision, adhesion, and detachment.

Figure 4. If the contact angle is very small, then the bubble does not attach to the surface, while a very large contact angle results in very strong bubble attachment. A contact angle near 90° is sufficient for effective froth flotation in most cases. Figure 4: Contact angle between and air bubble and a solid surface immersed in liquid.

The attachment process is dominated by the short- range surface forces and by the drainage and rupture characteristics of the thin liquid film between the bubbles and contacting particles.

Small-scale hard rock miners do not have the luxury of a fully equipped industrial-grade mill with flotation and cyanide leaching to process their ore and recover values. We are usually limited by practicality, finances and permitting to a simple crushing and grinding circuit, with a gravity recovery system for the free milling values and value ...

Flotation Frothers – Frothing Agents. The next reagent that is added is the Flotation FROTHER. The frother strengthens the surface tension of the air that is injected into the flotation cell. As the air rises in the shape of bubbles, they come into contact with the mineral laden collector which attaches itself to the air.

The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a ...

The process involves crushing the minerals into small particles, and then floating the particles in water to separate the commercially valuable particles from the waste rock. The water contains "collector" substances that can attach to the valuable particles, causing them to repel water and rise to the bubbling top of the water where they ...

Those minerals will attach to the air bubbles that are passing-by and rise to the surface of the tank just to get away from water. This is the process allowing us to separate minerals from waste rock. Flotation relies on differences in surface properties of different minerals to achieve separation.
