rdf:type	Mineral
rdfs:label	Trona
rdfs:comment	Trona (trisodium hydrogendicarbonate dihydrate also sodium sesquicarbonate dihydrate); Na 3(CO3 )(HCO3)•2 H2O is a non-marine evaporite mineral. It is mined as the primary source of sodium carbonate in the United States, where it has replaced the Solvay process used in most of the rest of the world for sodium carbonate production.
