  2. Crystallization - Wikipedia

    en.wikipedia.org/wiki/Crystallization

    Crystallization is the process by which solids form, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

  3. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Distillation, also classical distillation, is the process of separating the component substances of a liquid mixture of two or more chemically discrete substances; the separation process is realized by way of the selective boiling of the mixture and the condensation of the vapors in a still.

  5. Mass transfer - Wikipedia

    en.wikipedia.org/wiki/Mass_transfer

    Mass transfer is the net movement of mass from one location (usually meaning stream, phase, fraction, or component) to another.Mass transfer occurs in many processes, such as absorption, evaporation, drying, precipitation, membrane filtration, and distillation.

  6. Vein (geology) - Wikipedia

    en.wikipedia.org/wiki/Vein_(geology)

    The difference between 19th-century and 21st-century mining techniques and the type of ore sought is based on the grade of material being mined and the methods of mining which are used. Historically, hand-mining of gold ores permitted the miners to pick out the lode quartz or reef quartz, allowing the highest-grade portions of the lodes to be ...

  7. Fractionation - Wikipedia

    en.wikipedia.org/wiki/Fractionation

    Fractionation is widely employed in many branches of science and technology. Mixtures of liquids and gasses are separated by fractional distillation by difference in boiling point. Fractionation of components also takes place in column chromatography by a difference in affinity between stationary phase and the mobile phase.

  8. Crystallization of polymers - Wikipedia

    en.wikipedia.org/wiki/Crystallization_of_polymers

    Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by different analytical methods and it typically ranges between 10 and 80%, with crystallized polymers often called "semi-crystalline". The properties of semi-crystalline polymers are determined not only by the ...

  9. Mineralogy - Wikipedia

    en.wikipedia.org/wiki/Mineralogy

    Mineralogy applies principles of chemistry, geology, physics and materials science to the study of minerals. Mineralogy [n 1] is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.
