摘要： The invention relates to a method for producing a ferroalloy containing nickel. From a fine-grained raw material containing iron and chromium and a fine-grained raw material containing nickel, a mixture is formed with binding agent, the mixture is agglomerated so that first formed objects of desired size are obtained. The objects formed are heat treated in order to strengthen the objects so that the heat treated objects withstand conveyance and loading into a smelter furnace. Further, the objects are smelted under reducing circumstances in order to achieve ferrochromenickel, a ferroalloy of a desired composition containing at least iron, chromium and nickel.

摘要： A metallic article is produced by furnishing one or more nonmetallic precursor compound comprising the metallic base nickel, cobalt, iron, iron-nickel, or iron-nickel-cobalt, and at least one alloying element. The nonmetallic precursor compound(s) are chemically reduced to produce an initial metallic particle without melting the initial metallic particle. The initial metallic particle is thereafter melted and solidified to produce the metallic article. The melted-and-solidified metal may be used in the as-cast form, or it may be converted to billet and further worked to the final form.

摘要： A method of recovering copper and nickel from sulphidic minerals containing copper, nickel and iron comprises the steps of roasting the mineral, preferably to provide magnetite; sulphating, for example with sulphuric acid, sulphur trioxide, metal sulphate and/or sulphur dioxide together with oxygen; and a subsequent leaching of the sulphated material and recovery of copper from the leaching solution, for example by electrolysis. All or part of the leaching solution with its nickel content is recycled to the roasting stage, and the nickel content is removed in the form of nickel oxide together with the leaching residue, from which nickel can be recovered.
