Abstract
A lance (), for conducting a pyrometallurgical operation by top submerged lancing (TSL) injection, wherein the lance () has at least an inner pipe () and outer pipe () which are substantially concentric. The lower outlet of the inner pipe () is set at a level relative to the lower, outlet end of the outer pipe () required for pyrometallurgical operation. The lance () further includes a shroud () through which the outer pipe () extends and which is mounted on and extends along an upper portion of the outer pipe () to define with the outer pipe () a passageway () along which gas is able to be supplied for flow towards the outlet end of the outer pipe () for discharge exteriorly of the lance (). The shroud () is longitudinally adjustable relative to the outer pipe () to enable substantial maintenance of, or variation in, a longitudinal spacing between the outlet ends of the shroud () and the outer pipe ().
