Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain extraction as a separation process and its methods, describe applications in chemistry, food, pharmaceuticals and remediation, support method selection at a general level, and decline illicit or hazardous procedures.

A separation process in which a substance is removed from a mixture or matrix using a solvent, pressure, heat or other means, including solvent and solid phase extraction in chemistry, oil extraction by expeller pressing and supercritical carbon dioxide, microwave-assisted extraction, and phytoextraction in which plants remove metals from soil; extraction is fundamental in analytical chemistry, food and pharmaceutical processing, and environmental remediation, and is described here without procedures for illicit substances.

What it is for: Separating substances from mixtures.

It can be explain methods; describe applications; support method selection generally; decline illicit procedures.

What it looks like

Not physical as a concept; laboratory and industrial equipment.

How it is recognised

Removal of a substance from a matrix

Solvent, pressure, heat or plants

Distillation separates by boiling point; filtration separates solids; resource extraction is mining
