Abstract (en)
A burner and method for smelting metallic sulfide concentrates in a reverberatory furnace. The concentrates are passed through a central feed bore (14) of a burner. A blanketing shield of fuel is fed through a conduit (18) and envelopes the feed and thereby separates it from an oxygen-containing gas fed through a further conduit (22) prior to combustion. By shielding the feed from the oxygen, oxidation of sulfidic sulfur to sulfur dioxide is minimized.
