Claims
- 1. A reduced dusting pyrometallurgical system comprising a vessel, the vessel including a body, the body defining a central chamber therein, the vessel including a lower portion for holding molten material, a roof disposed above the lower portion of the vessel, and two opposed end walls, porous means for injecting inert gas extending through the lower portion of the vessel, the porous means for injecting inert gas adapted to form at least one bath eye in the molten material, an oxidizing gas lance positioned above the lower portion of the vessel so as to direct the oxidizing gas toward a sphere of influence of a bath eye, and means for drop feeding material into the vessel positioned above the lower portion of the vessel so as to direct the feed toward the sphere of influence of a bath eye.
- 2. The system according to claim 1 wherein a burner is disposed above the lower portion of the vessel and is directed toward the sphere of influence of a bath eye.
- 3. The system according to claim 2 wherein a burner is directly disposed above the porous means for injecting inert gas.
- 4. The system according to claim 1 wherein the oxidizing gas lance is reciprocative.
- 5. The system according to claim 1 wherein the oxidizing gas lance is disposed immediately above a molten material bath disposed within the vessel and directly above the gas injection means.
- 6. The system according to claim 1 wherein the oxidizing gas lance and the porous means for injecting inert gas are opposed and colinear.
- 7. The system according to claim 3 wherein a burner and a feeding means are both directly above the gas injection means.
- 8. The system according to claim 7 wherein a burner and a feeding means share a common vessel entry port.
- 9. The system according to claim 8 wherein the port is colinear with the injection means.
- 10. The system according to claim 1 including porous plugs disposed in the bottom portion of the vessel, the porous plugs connected to a gas supply.
- 11. The system according to claim 1 including exhaust gas means situated directly above the gas injection means.
- 12. The system according to claim 1 including means for rotating the vessel.
