Bismuth: extraction-Metalpedia

Ores containing the oxide and carbonate are treated either by smelting with carbon or by a wet process. In the wet process the ores, in which the bismuth is present as oxide or carbonate, are dissolved out with hydrochloric acid, or, if the bismuth is to be extracted from a matte or alloy, the solvent employed is aqua regia or strong sulphuric acid. The solution of metallic chlorides or sulphates so obtained is
