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.

Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated.

An object will float if the gravitational (downward) force is less than the buoyancy (upward) force. So, in other words, an object will float if it weighs less than the amount of water it displaces. This explains why a rock will sink while a huge boat will float .
Bench flotation test programmes are commonly designed to consider the following parameters: flotation kinetics, grind size, reagent selection and optimisation, selective flotation (complex sulphides), pulp potential and flowsheet design. Flotation is a physical-chemical process

Froth flotation commences by comminution (that is, crushing and grinding), which is used to increase the surface area of the ore for subsequent processing and break the rocks into the desired mineral and gangue in a process known as liberation, which then has to be separated from the desired mineral.
Main principle of separation, is the density difference between oil and water. In oily water mixtures, oil exists as a collection of globules of various sizes. Force acting on these globules, causing it to move in the water is proportional to the difference between the weights of oil particle and water particles.

Simply said; a Flotation Collectors is a chemical used to make the surface of minerals, which is metallic, hydrophobic or in laymans term afraid of water or water hating as others like to say. This chemical used will behaved, in a way, as a wax would when you applied it to your car. After wax (or hydrophobic agent) is adhered to the surface, that surface with see water pearl-away.
Frothers are non-ionic surfactants, commonly classified as alcohols and polyglycols, used in flotation . Alcohol types are generally considered as weak frothers having low surface activity (i.e., do not reduce surface tension much).
A venturi creates a constriction within a pipe (classically an hourglass shape) that varies the flow characteristics of a fluid (either liquid or gas) travelling through the tube. As the fluid velocity in the throat is increased there is a consequential drop in pressure.
However, the flotation operations are greatly benefit from a reduction in bubble size, through the increase in the probability of particlebubble collisions. For this reason, surfactant reagents (frothers) are commonly added to flotation systems.
Collectors attach themselves by polar groups to grains of some mineral and from water repelling films on those minerals . Hence, these minerals attach with vowels and go to froth.
pressure. Archimedes Principle is then brought in to show how the magnitude of the buoyant force is related to the volume of fluid that the object displaces. All concepts and ideas are backed up with interesting demonstrations and activities using fairly common objects. The students will get hands-on experience with fluid displacement, buoyant force, and Archimedes Principle.
The water cycle, also known as the hydrological cycle or the hydrologic cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water , saline water and atmospheric water is variable depending on a wide range of climatic variables .
Principle of operation: Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution)
