The act or operation of liquating or melting.

The condition or capacity of being melted: as, a substance congealed beyond liquation.

The separation of metals differing considerably in fusibility by subjecting them, when contained in an alloy or mixture, to a degree of heat sufficient to melt the most fusible only, which then flows away, or liquates, from the unmelted mass.

The act or operation of making or becoming liquid; also, the capacity of becoming liquid.

The process of separating, by heat, an easily fusible metal from one less fusible; eliquation.

The partial melting of a mixture of metals or ores in order to separate components
