摘要： Provided is a smelting method for producing metal by reducing a mixture that includes an oxide ore such as nickel oxide ore, wherein it is possible to improve productivity by raising the metal recovery rate as well as to inexpensively and efficiently produce high-quality metal. The present invention is a smelting method in which: an oxide ore and a carbonaceous reducing agent are mixed; the resulting mixture is heated and subjected to a reduction treatment; and metal and slag, which are reduction products, are obtained, wherein the reduction treatment is carried out in a state in which one or more surface deposits selected from carbonaceous reducing agents, metal oxides, and oxidation inhibitors are deposited on the surface of the mixture.

摘要： Systems and methods for processing sludge from a fume scrubbing system that scrubs fumes from a steelmaking converter in a manner that separates/isolates a significant portion of the metallic iron particles in the sludge and prepares these particles for convenient handling. In an exemplary system, the system includes separating equipment that isolates metallic iron particles in the sludge and forming equipment that forms the isolated particles into briquettes that have relatively high mechanical resistance that allow the briquettes to maintain their integrity during handling and storage. The high-metallic-iron-content briquettes can be recycled in the steelmaking process, for example, as charging material for a basic oxygen converter or an electric arc furnace. Water used in the system can be recycled and reused within the system, thereby making the system environmentally friendly.
Systems and methods for making pellet feedstock and sinter feedstock for making pig iron, and feedstocks made thereby. Nonmetallic particulates are isolated from steelmaking converter exhaust fume residue and are incorporated into the pellet and/or sinter feedstocks. In one embodiment, the nonmetallic particulates are disaggregated from metallic particles in the residue using an acoustic cavitation duct. In one example of making pellet feedstock, the nonmetallic particulates are mixed with iron ore, limestone, coal, and bentonite to form a mixture that is pelletized into green pellets, which are then cooked to form the pellet feedstock. In one example of making sinter feedstock, the nonmetallic particulates are first micro-pelletized and then mixed with iron ore, limestone, and coal to form a mixture that is then cooked and crushed to form the sinter feedstock.

摘要： Provided is a smelting method capable of effectively promoting a reduction reaction on pellets formed using nickel oxide ore as starting material to obtain a ferronickel alloy with a high nickel grade of at least 4%. The present invention is a method for smelting nickel oxide ore wherein ferronickel alloy with a nickel grade of at least 4% is obtained by reduction-heating of pellets formed from nickel oxide ore, the method comprising a pellet-producing step S1 for producing pellets from nickel oxide ore, and a reducing step S2 for reduction-heating of the obtained pellets in a smelting furnace. In the pellet-producing step S1, the pellets are produced by mixing nickel oxide ore with a specified amount of a carbonaceous reducing agent as starting materials. In the reducing step S2, the produced pellets are charged in a smelting furnace in which a carbonaceous reducing agent (furnace bottom carbonaceous reducing agent) has been spread over the entire furnace bottom and reduction-heating is performed.
