refining
Let an agent explain refining processes across industries, describe how specific materials are refined, address safety and environmental regulation, and separate figurative senses.
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 refining processes across industries, describe how specific materials are refined, address safety and environmental regulation, and separate figurative senses.
An industrial or chemical process that purifies a raw or intermediate material to a required grade by removing impurities, such as petroleum refining, metal refining including electrolytic zinc and copper refining, sugar and edible oil refining, and polymer devolatilization and sparging; refining produces marketable products and by-products and is regulated for safety and emissions.
What it is for: Purifying materials to grade.
It can be explain refining processes; describe refining of specific materials; address safety and environment; separate figurative senses.
