    摘要： A hydrometallurgical process for the treatment of a soluble silicate-bearing material for the recovery of its valuable metal content by leaching the silicate-bearing material at an elevated temperature with an aqueous solution of a mineral acid, precipitating silicic acid during the same stage in an easily settling and filtering form, the silicate-bearing material being added at such a rate that its concentration calculated as SiO.sub.2 corresponds to the simultaneously precipitating silicic acid quantity, and by finally separating the solid material from the valuable-metal-bearing solution.

    摘要： A process for the recovery of valuable metals from metallic alloys having iron as their principal constituent is disclosed in which the metal is leached by means of a sulfuric acid solution having such a concentration that a nearly saturated salt solution is obtained, and after the separation of a possible leach residue the solution is heated close to the boiling point, at which time an acid solution is added in an amount corresponding to the salt which has passed out of the solution, in order to crystallize the salt mixture, the crystallized material is separated from the solution and is decomposed under sulfating conditions, whereafter the metal salts are leached out from the iron oxide by means of water.

    摘要： The invention relates to a method for recovering zinc from a zinc oxide bearing material containing silicates. According to the method, the leaching of zinc compounds is carried out in circumstances where the silicates remain undissolved and consequently do not cause filtering problems. The silicate bearing residue is treated in a Waelz process, so that the major part of the silicic acid contained in the silicates is combined in the iron silicate slag formed in the Waelz process, and the zinc is returned into leaching mainly in oxidic form.

    摘要： According to the method of the invention, at least one or several of the metals nickel, cobalt and copper can be selectively precipitated as sulphide by aid of elemental sulphur from aqueous solutions containing other metals such as zinc. The temperature of the reaction is above the melting point of sulphur. The precipitation is carried out with a pH value below 2. The metals to be precipitated can be present in the solution either as oxides or sulphates. If the metals are sulphates, the sulphide of at least one of the metals is prepared to crystal seeds in the solution before precipitation.

    摘要： The purpose of the method is to remove chlorides and fluorides from a valuable metal raw material by leaching the raw material into sulphuric acid solution and by crystallizing the valuable metal sulphate selectively out of the solution. The valuable metal sulphate crystals are washed in sulphuric acid solution, and the recovered dechlorinated and defluorinated crystals are leached into water and conducted into electrolysis. The sulphuric acid solution employed in the raw material leaching and in the crystal washing is preferably the same as the return acid of the electrolysis. Chlorides and fluorides are removed from the mother liquor of crystallization in the bleed.
