Procedure and mechanism to reduce the pyrite content of coals for the purpose of reducing the sulfur oxide content of exhaust gases. [Process based on disintegration of coal into light component essentially free of pyrite and heavy-pyrite-rich component followed by dry separation of latter according to density] (in Translated from German (10 Aug 1969))
