What Is an Emulsion? Definition and Examples

In other words, an emulsion is a special type of mixture made by combining two liquids that normally don& 39;t mix. The word emulsion comes from the Latin word meaning "to milk" milk is one example of an emulsion of fat and water . The process of turning a liquid mixture into an emulsion is called emulsifi ion.

Emulsion - Wikipedia

Emulsions are used to manufacture dispersions – production in an emulsion & 39;phase& 39; has a number of process advantages, including prevention of coagulation of product. Products produced by such isations may be used as the emulsions – products including primary components for glues and paints.

Emulsion - Meaning, Types of Emulsion, Properties, Examples

The term emulsion is also applied to a group of mixed systems called as solutions, or gels or suspensions. Take, For example, the photographic emulsion is a gelatin gel consisting of tiny crystals dispersed in it. Some other examples of emulsions include butter which is an emulsion of water in fat and egg yolk containing lecithin.

Understanding charging and blasting solutions for mines and ...

This process is then repeated until the desired tunnel length is reached. Explosives must be charged in order to detonate. All high production underground operations use modern site sensitised emulsions with original emulsion water gel now playing a relatively in minor role.

Viscosity of emulsion can be varied by changing type of fuel oil used. Therefore emulsion explosives can be made in cartridge form of various sizes or can be used as bulk explosive in opencast as well as in underground workings. The ultra fine air bubbles or artificial air bubbles used as gassing agent acts as sensitiser.

With lower gold grades beneficiation usually flotation is often used ahead of leaching to increase the grade of Au and reduce the quantity of ore to be leached. Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and ...
