A method for the pyrometallurgical processing of a sulphide material containing copper, the sulphide containing relatively high quantities of silica and relatively low quantities of iron, wherein the process comprises feeding the sulphide material to a TSL furnace operated under oxidising conditions such that the sulphide material forms blister copper containing between 1.2 and 1.5 wt % sulphur and a slag containing between 7 and 13 wt % copper.

Method for treating copper concentrates

An arrangement () for preventing egress of a gas from a first opening of a vessel, the vessel including at least one other opening through which the gas can leave the vessel, the arrangement comprising an open passage () extending substantially around the first opening, the open passage () receiving a flow of gas such that the flow of gas leaves the open passage and flows towards and into the vessel to cause a gas from the environment external to the vessel to be drawn into the vessel. The arrangement may comprise a Coanda surface. The arrangement may be in the form of an inert for placement in the opening to the furnace.

Method and arrangement for preventing gas from leaving an opening of a vessel

A method for the pyrometallurgical processing of sulphide material containing nickel using a fluxing composition that includes calcium. The fluxing composition forms a slag having an Fe/CaO ratio of between about 0.5 and 5.0 by weight and an SiO/Fe ratio of less than 0.2 by weight.
