14 SEPARATION TECHNIQUES

14 SEPARATION TECHNIQUES 14.1 Introduction The methods for separating, collecting, and detecting radionuclides are similar to ordinary analytical procedures and employ many of the chemical and physical principles that apply to their nonradioactive isotopes. However, some important aspects of the behavior of radionuclides are

Physical Separation Methods

Since there is no chemical reaction involved, the constituents retain their original properties. In the formation of a mixture, there is no loss or gain of energy. We can easily separate the components of a mixture using physical methods. Separation of The Constituents of A Mixture. A mixture is formed as a result of a physical change.

Separating Mixtures | Physical Separation Techniques ...

The Separation process is used to transform a mixture of substances into distinct products. Mixtures are the product of mechanical blending of chemical substances such as elements and compounds, without formation of any chemical bond or change in the individual components, so that each constituent can retain its original state.

Refined coal

Refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned.

Physical and chemical coal cleaning: AIP Conference ...

 · While physical methods are very effective and low in cost when applied to the separation of coarse particles, they are much less effective when applied to the separation of fine particles. Also they can not be used to remove impurities which are bound chemically to the coal. These deficiencies may be overcome in the future by chemical cleaning.

Uranium processing | Britannica

Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.
