摘要： There is provided a method for recovering indium, the method being capable of recovering indium having a high purity at simple and inexpensive steps in a short time and with a high recovery. After indium containing substances, such as ITO target scraps, are crushed, the crushed substances are ground until the percentage of coarse particles having a larger particle size than a predetermined particle size is not larger than a predetermined percentage. Thereafter, the ground substances are dissolved in an acid, and the solution thus obtained is neutralized with an alkali so that the pH of the solution is 0.5 to 4. Then, the solution is aged at a temperature of 60 to 70° C. for 3 hours or longer to deposit and remove hydroxides of predetermined metal ions in the solution. Then, hydrogen sulfide gas is blown into the solution to deposit and remove sulfides of metal ions which are harmful to electrolysis at the subsequent step, and thereafter, the solution thus obtained is used as an electrolytic solution for electrowinning indium metal to recover indium having a high purity.

摘要： Improved methods for treating metallurgical compositions involve reacting a metallurgical composition with an aqueous nitric acid solution. The reaction is performed at a pressure of at least about 220 psig and at a temperature of at least 100° C. The metallurgical composition comprises iron and one or more non-ferrous metals. The reaction dissolves the majority of the non-ferrous metal compositions into the solution which is in contact with solid ferric oxide. The reaction can be repeated on the isolated solids to increase the purity of ferric oxide in the solids. Zinc can be removed from the mixed metal solutions obtained from furnace dust by a variety of separation techniques.

摘要： The present invention is a method of recovering valuable metals from a quantity of furnace dust consisting the following steps. A first leaching step wherein the furnace dust is leached at atmospheric pressure in a first leaching solution to produce a first leach liquor and a first leach residue, the first leaching solution consisting of an aqueous mineral acid solution. The first leach liquor is then separated from the first leach residue. A second leaching step is then performed wherein the first leach residue is atmospherically leached in a second leaching solution to form a second leach liquor and a second leach residue, the second leaching solution comprising a solution of aqueous HCl with a reductant. The second leach liquor is then separated from the second leach residue. A zinc precipitation step is then performed wherein zinc is precipitated from the second leach liquor by treating the second leach liquor with a quantity of alkali, the quantity of alkali selected to adjust the pH of the second leach liquor sufficiently to precipitate out the zinc in the form of a zinc salt in a third residue leaving a third liquor and then separating the third residue containing zinc from the third liquor.

摘要： A method of recovering valuable materials from lithium batteries wherein a lithium/transition metal composite oxide is used as a positive electrode active material. In this disposal method, a sheeted positive electrode having a positive electrode active material disposed on a positive electrode collector is immersed in an oxalic acid solution. By virtue of this oxalic acid treatment (step 240), any lithium element contained in the positive electrode active material can be leached into the oxalic acid solution. Using oxygen gas produced by a reaction between the positive electrode active material and oxalic acid, attachments, such as the positive electrode active material, can be self-detached from the positive electrode collector. The transition metal element contained in the positive electrode active material is converted by the oxalic acid treatment to insoluble transition metal compounds (oxalate, oxide, etc.). Thus, though simple means such as filtration (step 244), the leached lithium element can be easily separated from the insoluble transition metal element.

摘要： A process for reclaiming spent selenium filter mass containing an inert material, following take-up of mercury by a substance which contains selenium and is present in the filter mass. The spent mass is treated with a hydrogen peroxide solution for leaching out of the selenium content in essentially all unspent active substance present in the mass to form selenious acid. The resulting selenious acid is separated and isolated for use. The mass freed of the solution is treated with aqua regia for dissolving essentially all of the mercury selenide present in the mass. The aqua regia solution with its content of mercury and selenium are separated from the mass and isolated. Suitably, after it has been washed and dried, the mass freed of the aqua regia solution, which now only contains inert carrier material, and also the previously isolated selenious acid, are transferred to production of new selenium filter mass. After partial neutralisation of the solution, mercury is precipitated in a form that allows it to be deposed. Before that, selenium can be selectively separated and obtained from the aqua regia solution after its pH value has been adjusted, and isolated as elemental selenium useful for the production of new filter mass. Reclaimed selenium content and inert carrier material contained in the filter can advantageously be used for the production of new selenium filters.

摘要： The present invention springs from the discovery that mild acids could be utilized to shear undesired metals away from desired precious metals that have been plated onto circuit board runners or contacts. This shearing action occurs at a high rate when metal scrap segments are immersed in mild acid and excited by application of an electromagnetic field at specific frequencies and power levels. These frequencies and power levels are based on the end metal desired and the metals contained in the scrap and the acid utilized. When mild acid saturated with copper sulfate and loaded with scrap metals is subjected to an electromagnetic field at the appropriate frequency and power levels, copper and nickel molecules are sheared rapidly and absorbed into solution, leaving only the desired metal, such as gold, in a 99.5% pure flake which can be skimmed off the surface of the solution or filtered from the solution. The captured metal flake is then rinsed in water and denatured alcohol, compressed, melted and poured into bars or nuggets for further use or sale.

摘要： A method for processing alumina-bearing ores such as bauxite to recover iron, aluminum, silicon and titanium metal values therefrom the method comprising the steps of adding the alumina-bearing ores to a digester containing an acid to provide a mixture of acid and alumina-bearing ores and heating the mixture to dissolve soluble compounds of at least one of iron, aluminum, silicon and titanium to provide a digest containing dissolved salts of the soluble compounds and to provide a gas component. Thereafter, the digest is treated with water to dissolve water soluble salts therein to provide a slurry comprised of a liquid containing water and the dissolved soluble salts and a solid component comprised of silica. The solid component is separated from the liquid and the pH of the liquid is adjusted to form an aluminate and an iron-containing precipitate. The iron-containing precipitate is separated from the liquid to provide an iron-depleted liquid whose pH is adjusted to precipitate aluminum trihydrate which is separated from the iron-depleted liquid to provide an aluminum trihydrate-depleted liquid. The pH of the aluminum trihydrate-depleted liquid is adjusted to form a precipitate comprised of at least one remaining salt in the aluminum trihydrate-depleted liquid to provide a salt-depleted liquid. The salt precipitate is separated from the salt-depleted liquid thereby recovering the metal values from the alumina-bearing ores.
