A furnace assembly for the pyrometallurgical treatment of fine-grained ore concentrates including a housing in which there is located a reactor for reacting an ore concentrate and an oxygen-rich gas admitted thereto, the housing further having means therein defining a collection chamber for collection of the molten metal and a settling hearth in the housing communicating with the collection chamber. The housing is provided with a downwardly offset wall means in the roof thereof and partition means in dependent relationship with such offset wall means. The partition means are positioned to isolate the upper portion of the collection chamber from the settling hearth. An exhaust stack is provided transversely with respect to the long dimension of the settling hearth.

Furnace installation for the pyrometallurgical treatment of fine-grained

Method and apparatus for the thermal treatment of slurries such as slurries of magnesite hydrate or the like. The method involves suspending the slurry in an airstream, passing the airstream with the suspended slurry particles into contact with a heated gas stream in a dryer, passing the thus-dried slurry to a multi-tiered heated kiln, introducing heated gases into the kiln for drying contact with the thus dried slurry, and passing the exhaust gases from the kiln to the dryer to serve as the heated gas stream.

Method and apparatus for treating slurries

The method and mechanism for thermally treating a slurry of material such as a magnesite hydrate wherein a kiln housing has an upper chamber portion and a lower chamber portion with spray nozzles in the roof of the upper chamber for directing a spray of slurry downwardly and a rotor with arms in the lower portion and separators forming a plurality of tiers in the lower portion with heated gases directed tangentially into the chamber at the base of the upper portion and additional gases directed into the lower portion with the heat treated material being drawn from the base of the chamber and evaporated moisture withdrawn from the top of the chamber, and dust separated from the moisture and reintroduced into the chamber.
