sulphides
Metal sulfur combinations
Sulphides are chemical compounds containing sulfur bonded to a metal or other element.
The term appears in chemistry and mineralogy: iron sulphides, hydrogen sulphide.
Sulphide is the British spelling; American English uses sulfide.
Many sulphides occur naturally as ores—galena (lead sulphide) and pyrite (iron sulphide) among the most familiar.
