liquation

Physics

The separation of mixtures of solids by heating to a temperature at which lower-melting components liquefy.

Chemistry

The separation of mixtures of solids by heating to a temperature at which lower-melting components liquefy.

Chemical Engineering

A separation and purification process used for metals from ores. It involves heating to a temperature at which the lower melting metals liquefy and can then be separated by draining. It was once used to separate lead containing silver from copper in the fifteenth century. The lead melts at 327°C whereas copper melts at 1,084°C allowing the silver-rich lead to melt and freely drain away. To avoid oxidation, the liquation furnace operates with a reducing atmosphere.

Geology and Earth Sciences

A form of magmatic differentiation in which a sulphide liquid separates from a mixed sulphide–silicate magma and sulphide droplets sink to the bottom of the intrusion or lava flow, where they accumulate. The sulphide liquids have a strong affinity for nickel, copper, iron, and platinum-group elements. Consequently, liquation produces valuable orebodies.
