摘要： PURPOSE:To separate and recover high purity Li in a high yield by separating Li in bittern with an H-type cation exchange resin and adding a soln. contg. OH or CO3 to a soln. used to elute the Li to precipitate the Li. CONSTITUTION:Bittern is fed to an H-type cation exchange resin column, and after washing with distilled water Li and Na are eluted with 1N HCl. An ammonia soln., alkali hydroxide, ammonium carbonate or alkali carbonate is added to the eluate to precipitate the Li as lithium hydroxide or lithium carbonate. This precipitate is then dissolved in hydrochloric acid, and the soln. is evaporated to dryness to recover the Li as lithium chloride.

摘要： PURPOSE:To separate Th in high yield by a method wherein fine powder of monazite is dissolved with acid by heating, aq. NH3 or NaOH is added to precipitate hydroxide, the precipitate is dissolved in HCl then treated with ion exchange resin, and HCl of a specified concentration is used for cleaning and elution. CONSTITUTION:Fine powder of monazite contg. ThO2, etc. is dissolved in acid by heating, undissolved residue is filtered out, the filtered solution is added with aq. ammonia or sodium hydroxide to precipitate hydroxide. The precipitate is dissolved in HCl and the concentration of acid is maintained below 4N. The HCl solution is flowed into a cation exchange resin column, the resin column is cleaned with 4N HCl, then Th is eluted by 8-12 N HCl, the eluted solution is added with aq. ammonia to precipitate Th hydroxide. The precipitate is calcined in an electric furnace to separate and recover high-purity thorium oxide in high yield. The process in this method is simpler than the conventional caustic soda method.

摘要： PURPOSE:To obtain Ni, Co and copper of high purity by adding glycol ether diamine tetraacetic acid or other to the acid solution of manganese nodules, passing the solution through cation exchange resins then adding a rubeanic acid, dissolving the precipitate thereof in an acid and eluting Ni, Co and copper through anion exchange resins. CONSTITUTION:Manganese nodules are dissolved in an acid and glycol ether diamine tetraacetic acid or cyclohexane diamine tetraacetic acid as a chelating agent is added to this solution, which is then passed through anion exchange resins. The eluate thereof is controlled to pH6 and is then added with rubeanic acid to allow Ni, Co, and copper to precipitate, whereby a large amount of iron, Mn and lead are removed. This precpitate is dissolved in a nitric acid and the solution is evaporated to dryness. The solid is dissolved in a 9N hydrochloric acid and is passed through cation exchange resins and the 9N hydrochloric acid is flown away to elute Ni and copper. Next, Co is eluted by using a 4N hydrochloric acid.

摘要： PURPOSE:To separate and recover Ni, Co, copper at a high yield from manganese nodule by dissolving the manganese nodules in acid. adding a rubeanic acid to separate Ni, Co, copper, performing adsorption, elution process by making the use of iron exchange resin. CONSTITUTION:The manganese nodules are dissolved in hydrochloric acid or the like and the insoluble contents are filtered away. The solution is then controlled to around pH 6, to which a rubeanic acid solution is added and the solution is heated to 60 to 70 deg.C to allow Ni, Co, copper to precipitate, thence the greater part of Mn and iron is removed. This precipitate is dissolved in a concentrated nitric acid or the like and is evaporated to dryness, after which it is dissolved in a dilute bydrochloric acid and the solution is next passed through a cation exchange resin column to allow the remaining iron and Al to be adsorbed and removed. next, the solution is passed through an anion exchange resin column to let the metal components be adsorbed. Following to this, Ni is eluted by a hydrochloric acid of 0.5 to 10.5 normality and Co and copper are eluted by a hydrochloric acid of 3.5 to 4.5 normality.

摘要： PURPOSE:To improve the purity and yield of each recovered metal by adjusting a soln. of an Sm-Co alloy to 3 pH, separating a precipitate of an Sm compound from an aqueous soln. of a Co compound, and separately treating them. CONSTITUTION:A soln. of an Sm-Co alloy is adjusted to 3 pH by adding trisodium phosphate and sodium hydroxide, and a precipitate of an Sm compound is separated from an aqueous soln. of a Co compound. The precipitate is dissolved in an acid, oxalic acid is added to the soln. to precipitate Sm oxalate, and Sm oxide is recovered by calcining the Sm oxalate at about 1,000 deg.C. Sodium hydroxide is added to the Co compound soln. to precipitate Co hydroxide, and Co oxide is obtd. by calcining the Co hydroxide at about 1,000 deg.C.
