摘要： PURPOSE:To separate and recover high-purity nickel sulfate in high yield by neutralizing and removing copper and sulfuric acid from a copper electrolyte, then neutralizing and settling impurities except Ni, removing the residual impurities by solvent extraction from the filtrate, further removing Ni by the solvent extraction, thickening the Ni extraction liquid and removing moisture therefrom. CONSTITUTION:The free sulfurin acid in the copper electrolyte in which the content of the impurities increases is neutralized by a known method and the copper is recovered in the form of copper sulfate therefrom; in succession, the pH is neutralized to 0-3 by CaO, etc., to allow the greater part of Sb, and Bi to settle and at the same time, the free sulfuric acid is removed in the form of gypsum. A neutralizing agent such as CaCO3 is added to the filtrate to adjust the pH to 5-6.5 and to settle and remove Fe, part of residual Cu and Zn and As and Pb in the form of hydroxide. The residual Cu, Zn, and Ca are removed from the filtrate by using a solvent such as di-2-ethyl hexyl phosphoric acid, etc., for said liquid. The residual liquid is neutralized to 5-7 pH by NH4OH, etc., and the Ni is extracted by the above-mentioned solvent. The extraction liquid is thickened while said liquid is subjected to a reverse extraction by sulfuric acid. The crystal of the high-purity nickel sulfate is thereafter formed and is recovered by a well-known method.

摘要： PURPOSE: To extract Sb and Bi from an aqueous solution acidified with sulfuric acid, in high extraction yield and selectivity, by contacting the solution containing Sb and Bi with a solution of a specific tricarboxylic acid ester in a water- insoluble solvent.
CONSTITUTION: A tricarboxylic acid ester of formula (R
1 , R
2 and R
3 are 4W18C alkyl) (e.g. phosphonobutane-1,2,4-tricarboxylic acid butyl ester) is dissolved in a water-insoluble solvent (e.g. kerosine). The obtained solution is used as an extractant, and is made to contact with an aqueous solution containing Sb and Bi and acidified with sulfuric acid to effect the selective extraction of the Sb and Bi from the solution. The Sb and Bi extracted to the water-insoluble solvent solution can be recovered by the back extraction of the solution with hydrochloric acid. The process of the present invention can be suitably applied for the separation of Sb and Bi existing as impurities in the electrolyte in the electrolytic refining of copper.

摘要： PURPOSE:To selectively separate and remove Sb and Bi from the titled soln. by simple operation by adding an oxidizing agent to the soln. in a stage for electrolytically refining copper. CONSTITUTION:A copper anode used in an stage for electrolytically refining copper contains impurities such as Sb and Bi. In the stage, part of the impurities is leached out, accumulates as impurities in an electrolytic soln. and hinders the electrolysis of copper. In order to selectively separate Sb and Bi from the copper electrolytic soln., an oxidizing agent such as hydrogen peroxide is added to the soln. The soln. freed of Sb and Bi by treatment with the oxidizing agent is sent to a stage for electrolytically removing copper as it is. Since only the oxidizing agent is added, sulfuric acid is not consumed and a different kind of metal does not enter the soln.
