Also known as purification, refinement, chemical purification, chemical refining, chemical refinement
Refining is the process of purification of a (1) substance or a (2) form. The term is usually used of a natural resource that is almost in a usable form, but which is more useful in its pure form. For instance, most types of natural petroleum will burn straight from the ground, but it will burn poorly and quickly clog an engine with residues and by-products. The term is broad, and may include more drastic transformations, such as the reduction of ore to metal (for which see Refining (metallurgy)).

Raffinering (från franskans raffiner, av fin, fin) är en generell beteckning på kemisk-tekniska reningsprocesser. Man kan till exempel raffinera socker, metaller och olja. För industriell raffinering använder man sig av ett raffinaderi.
