Extraction may be a process of choice when: Distillation cannot be used if the components to be separated have close boiling point temperatures or the components to be separated are heat sensitive. The amount of solute is very less in the feed itself, in essence a dilute liquid mixture.

Bayer process is a leaching process of bauxite. This process is use to produce high purity alumina (needed in subsequent electrolysis process) by leaching bauxite by NaOH. Leaching is done in autoclave at high presuure ( 25-30 atm) and high temperature (220 o C), which produces a soluble aluminate (2NaAlO 2 ), and from which we precipitate out ...

The extraction process goes through several stages: 1. When coffee grounds first meet water, the first compounds to be released create fruity and acidic notes. If you were to stop the extraction process here, most cups would end up tasting thinner or sour. 2. Sweeter, nuttier notes and rich mouthfeel come next as more sugars and lipids are ...
