摘要： The invention relates to a method for separating nickel and other valuable metalsparticularly from material having low nickel content, which contains iron and magnesium in addition to nickel and other valuable metals.The material havinglow nickel content is subjected to pulpingand atmospheric leaching in acidic and oxidising conditions, in which the majority of the metals in themate- rialdissolve and the iron is partially precipitated. The precipitated iron is sepa- rated from the solution, after which nickel and the other dissolved valuable metalsare precipitated as sulphides.

摘要： The invention relates to a method for processing pyritic copper sulphide concentrate, in which, in addition to copper, there is arsenic and gold bound to the sulphide minerals, or invisible gold. In the method concentrate is leached into a chloride-containing solution. Raw material leaching is performed in conditions where the copper, iron and arsenic of the raw material dissolve, but the gold-containing material remains undissolved. The chloride solution obtained is routed to neutralisation, where the iron and arsenic in it are precipitated. The purified copper solution is routed to liquid- liquid extraction, in the stripping stage of which copper is transferred to a sulphate solution, which is routed to copper electrowinning. Gold is recovered from the leaching residue by some known method.

摘要： The invention relates to a method by which the valuable metals and any possible precious metals are recovered from a material containing them, such as the mixed matte formed in a smelter. The valuable metals in the material formed in the smelter are leached with an acidic solution containing sulphate and chloride, from which each metal is separated by means of solvent extraction. In leaching,any precious metals contained in the material remain undissolved in the leach residue, from which they are leached with a solution containing hydrochloric acid in oxidizing conditions and separated from the solution by solvent extraction.

摘要： The invention relates to the hydrometallurgical treatment of laterite ores in order to recover valuable metals. More specifically, the invention presented relates to a method for improving precipitation and solid-liquid separation in conjunction with the leaching of laterite ores. According to the method the slurry exiting the leaching of laterite ores is neutralised, after which part of the slurry is routed to solid-liquid separation. Iron is precipitated from the solid-liquid separation overflow by neutralising the solution and the solution that is formed, which includes jarosite seeds, is routed to an appropriate point in the process to control the precipitation of iron and to enhance the filterability of the solids.

摘要： The invention relates to a method for processing concentrates, particularly concentrates produced from copper sulfide-based ores. According to the method, the concentrate (4) to be processed, obtained from ore concentration, is divided into two parts, to a concentrate (7) mainly containing poorly soluble components, and to a concentrate (8) mainly containing well soluble components. The concentrate (8) containing well soluble components is conducted to a leaching step (9), and the solution (13) obtained from said leaching step is conducted to at least one conversion step (11, 16), and to the conversion step (11) that is located first in the flowing direction, there is fed the concentrate (7) containing poorly soluble components. In the conversion step (11) that is located first in the flowing direction, at least the copper contained in the solution is converted into sulfidic form by means of the sulfide-form iron of the concentrate (7) containing poorly soluble components, and at least part of the solution (12) obtained from the conversion step (11, 16) is returned to the leaching step (9).

摘要： The invention relates to a method for leaching a material containing a valuable metal and precipitating the valuable metal as a fine-grained powder by changing the electrochemical potential of an intermediary metal in the solution. In the leaching stage the intermediary metal or substance of the electrolyte solution is at a high degree of oxidation and in the precipitation stage another electrolyte solution is routed into the solution, in which the intermediary metal or substance is at a low degree of oxidation. After the precipitation stage the solution containing the intermediary is routed to electrolytic regeneration, in which part of the intermediary is oxidised in the anode space back to a high potential value and part is reduced in the cathode space to its low value.
