What does unmixing mean?
Unmixing is the act or process of separating something that has been combined into its constituent parts. In literal use, it may refer to separating ingredients, chemical compounds, mixed signals, or other materials so that they can be examined individually. For example, laboratories use specialised equipment for the unmixing of chemical mixtures, while signal-processing systems perform source separation to distinguish overlapping recordings. The word can also be used figuratively for identifying or disentangling different ideas, influences, or problems within a complex situation. Its connotation is generally neutral or mildly technical, although figurative uses may imply clarification and order. Unlike “mixing,” which emphasizes combination and integration, “unmixing” reverses that process and exposes the elements involved. Although less common than “separating” or “sorting” in general speech, it is useful when the mixture or combination itself is especially noticeable.
The process or act of separating a mixture into its constituent parts, or of disentangling elements that have been combined.

Unmixing reveals what was hidden in a mixture—and sometimes untangles a problem that seemed deliberately complicated.

Where does unmixing come from?
“Unmixing” was formed in English during the 19th century by adding the prefix un- to “mix.” The prefix here reverses or undoes the action expressed by “mix,” whose own roots lead through Old French to Latin mixtare, meaning “to mix.” Related English forms include “mixed,” “mixture,” and “mixer.”
