  • Patent number: 4732368
    Abstract: Process and apparatus for pyrometallurgically treating finely divided ores, concentrates, residues, slags and like materials. The process utilizes a reactor having two co-axially extending, vertical reaction chambers. The process comprises forming within the upper chamber of the reactor hot fuel-rich reaction gases; passing the hot fuel-rich reaction gases by dump flow into a second vertically extending chamber; introducing into the second chamber the finely divided materials to be treated; and reacting the finely divided materials with the hot fuel-rich reaction gases. The dump flow of hot fuel-rich reaction gases passing into the second chamber is produced by providing a zone of sudden expansion in the flow passage between the first and second chambers.
    Type: Grant
    Filed: November 12, 1986
    Date of Patent: March 22, 1988
    Assignee: St. Joe Minerals Corporation
