    摘要： Provided is a method for transporting reductant such as coke into a metallurgical furnace containing a bottom layer containing molten metal and a top layer on top of the bottom layer containing molten metal. The method comprises a first providing step for providing reductant, a second providing step for providing metal, a forming step for forming carriers containing reductant and metal of reductant provided in the first providing step and metal provided in the second providing step, and a feeding step for feeding carriers formed in the forming step into the metallurgical furnace. Also provided is a carrier and a production method for producing carriers.

    摘要： A method and arrangement of separating arsenic and optionally antimony from a starting material, comprising -a low acid leaching step for leaching a first part of iron, arsenic, copper and optionally antimony, into the first leaching solution, -a first solid-liquid separation step, wherein a first solid leach residue is separated from the first leach solution, -a high acid leaching step for leaching a second part of iron, arsenic, copper and optionally antimony into the second leach solution, -a second solid-liquid separation step for obtaining a second solid leach residue and the second leach solution is recycled back to the low acid leaching step, -a precipitation step for obtaining a precipitate comprising ferric arsenate and optionally antimony compounds, and -a third solid-liquid separation step, wherein the solution comprising copper is separated from the obtained precipitate.

    摘要： The invention relates to a method for processing slags of non-ferrous metallurgy,containingiron and valuable metals,to produce clean slagthatis free of detrimental substances and valuable metals and suitable as it isfor use as a raw material or construction material. Slag is reduced in a reduction furnace (18) with the help of reducing agents (19) so far that at least 5% of the iron ofthe slag is reduced into metal. At the same time, some of the valuable metals, such as zinc, lead, arsenic and cadmium, vaporize. The contents ofthe reduction furnace (18) arecontinuously mixedto prevent separation of a metallic phase from the slag. The generated slag-metal mixture (21) is tapped off from the reduction furnace (18), cooled, crushed and ground to a finer size. Finally, a metal fraction (26) is separated from a clean slag (25).
