Zusammenfassung:	PCT No. PCT/AU90/00466 Sec. 371 Date Mar. 20, 1992 Sec. 102(e) Date Mar. 20, 1992 PCT Filed Sep. 26, 1990 PCT Pub. No. WO91/05214 PCT Pub. Date Apr. 18, 1991.A lance comprising a first elongate tube extending through an elongate tubular shroud, is used for top submerged injection of a fluid into a liquid pyrometallurgical bath comprising slag or having slag on its surface. The first tube defines a duct for the flow of the fluids. The shroud defines a flow passage for a coolant such as air. The shroud terminates above the lower end portion of the first tube. In use, the coolant cools the lance and discharges into the bath when the outlet of the first tube is inserted into the bath.
