Extraction and Occurrence of Sulphur

Vocabulary flashcards detailing the natural occurrence of sulphur and its extraction using the Frasch process based on the lecture notes.

Underground sulphur beds

Underground deposits where sulphur freely occurs in nature.

Metal ores

Important ores formed when sulphur combines with metallic elements.

Hydrogen sulphide

A compound in natural gas from which sulphur can mainly be obtained.

Petroleum

A natural resource in which sulphur is also found.

Frasch process

The method used for the extraction of sulphur from underground deposits using superheated water and compressed air.

Superheated water

Water heated above $100^\circ C$ used in the Frasch process to melt underground sulphur rock.

Hot compressed air

Air forced down through the innermost pipe in the Frasch process to lift molten sulphur to the surface.

Molten sulphur

The liquefied form of sulphur produced underground by superheated water and brought to the surface.
