    摘要: The invention relates to a method and to an arrangement for feeding fine-grained matter to a concentrate or matte burner (1) of a suspension smelting furnace (2). The arrangement comprising a fluidization arrangement (3) for feeding fluidized fine-grained matter into a dosing bin (4), and a conveyor means (6) for feeding fluidized fine-grained matter from the dosing bin (4) to the concentrate or matte burner (1) of the suspension smelting furnace (2), and a loss-in-weight controller (5) between the dosing bin (4) and the conveyor means (6). The arrangement comprises an impact cone (8) arranged below a filling valve (7) between the fluidization arrangement (3) and the dosing bin (4) for distributing fluidized fine-grained matter flowing from the fluidization arrangement (3) within the dosing bin (4).

    摘要: Copper is produced by a looping oxidizing process wherein oxidation of copper sulfide concentrate to molten blister copper by conversion with copper oxides (and optionally oxygen from air) in a one step, molten bath operation to produce molten blister copper, iron oxide slag, and rich SO2 off gas. The blister copper is treated in an anode furnace to reduce the iron content and oxidize residual sulfur, and prepare it for either electrolysis or reoxidation.

    摘要: Smelting is effected in a reactor containing juxtaposed oxidizing and reducing zones. The slag baths in the two zones communicate with each other. The slag baths of the two zones communicate with each other, the materials are charged into the slag bath in the oxidizing zone and oxygen-containing gases are blown into the slag bath in the oxidizing zone, a slag which is rich in non-ferrous metal oxides is passed from the oxidizing zone into the reducing zone, reducing agent and oxygen-containing gases are blown into the slag in the reducing zone at such respective rates that the non-ferrous metal oxides are substantially completely reduced and a phase that is rich in non-ferrous metal is formed, a slag which is poor in non-ferrous metal is tapped from the reducing zone, gases are separately sucked from the oxidizing and reducing zones, and the subatmospheric pressures in the suction lines connected to the oxidizing and reducing zones are so controlled that a zero differential pressure is obtained adjacent to the boundary between the oxidizing and reducing zones.
