What does scorification mean?
Scorification is a technical metallurgical process used to treat ore or mineral material with heat and a suitable flux. Much of the rock or other nonvaluable material then combines with the flux, producing a fusible slag that can be separated from the useful metallic material. In assay work, this may leave a metallic button or concentrated matte for further testing. The word belongs primarily to metallurgy, mineral processing, and the vocabulary of analytical laboratories. Although scorification can resemble roasting or smelting, its defining feature is the conversion of unwanted constituents into slag while concentrating the valuable metal. It is especially associated with historical fire-assay methods and with the examination of ores and concentrates.
nounA metallurgical process in which ore or another mineral material is heated with a flux so that much of its nonmetallic or earthy material combines with the flux to form fusible slag. The process is also used in assaying to separate or concentrate valuable metals.
- The process of heating ore or mineral material with a flux so that earthy or nonmetallic constituents form fusible slag.
- An assay technique in which metallic constituents are concentrated into a button or matte for further examination.
"The ore was examined by scorification to determine the amount of recoverable metal it contained."
"Scorification of the concentrate produced a lead button for subsequent cupellation."
"The laboratory recorded the temperature and duration of each scorification."
The plural is rare because the word usually refers to a process or technique rather than a countable object.
"The metallurgist compared several scorifications performed at different temperatures."
Scorification helped old assay workers turn ordinary-looking ore into slag and a precious-metal-rich button, revealing the ore's hidden value by fire.

Where does scorification come from?
Scorification was formed from the verb score, used in the sense of cutting, dividing, or exposing material, together with the suffix -ification, denoting the formation or conversion of something. The technical term developed through the vocabulary of metallurgy and assaying, where scorification describes heating mineral material with flux so that unwanted constituents are converted into slag. Its cognate verb, scorify, and the noun scorifier continue that specialized usage.

How scorification is actually used
A specialist term chiefly used in metallurgy, mineral processing, and historical or laboratory assaying. It describes both the treatment itself and, occasionally, the vessel in which it is performed.
Easily confused with scorification
Scorification primarily converts unwanted mineral constituents into slag while concentrating metal in a button or matte, whereas smelting generally aims to produce the metal itself.
