Refining By: Natalie Zoglman

What is refining? It is the purification of a substance or form.

What are some things that can be refined? Copper Iron Lead Precious metals (ores, alloys, etc) oil Etc.

Processes - cupellation - Pattinson process - fire refining - electrolytic refining - Bessemer process - etc.

Cupellation Metallurgical process Example: Extract silver from lead Cupellation furnaces after Agricola, 1556/1950

Pattinson Process Patented in iron pots Example: extract sliver from lead

Fire Refining Fire melting Example: 99.25% pure Copper

Electrolytic Refining Electrolysis Example: Creates % of pure copper

Bessemer Process Bessemer converter

Oil Refinery Crude oil Petroleum
