摘要： A method for producing an aqueous solution containing nickel, cobalt and manganese, includes: a leaching process including a pressure-leaching process of leaching a raw material under pressure to form a leachate containing nickel, cobalt, manganese and impurities; an impurity removal process of removing the impurities from the leachate; a target substance precipitation process of precipitating a mixed hydroxide precipitate containing nickel, cobalt and manganese by introducing a neutralizing agent into a filtrate from which the impurities are removed; and a dissolution process. The pressure-leaching process includes a first-stage pressure-leaching process and a second-stage pressure-leaching process of pressure-leaching a residue of the first-stage pressure-leaching process with an acidity higher than an acidity in the first-stage pressure-leaching process. The impurity removal process includes a first-stage solvent extraction process of selectively extracting zinc from the impurities and a second-stage solvent extraction process of selectively extracting magnesium from the impurities.

摘要： A method (2800) of selectively leaching one or more manganese-containing phases from a mixed-phase battery electrode material comprises treating (2802) the mixed-phase battery electrode material with a solution of an acid, the acid acting as both a leaching agent and a reducing agent, so as to form a manganese-containing leachate whilst leaving at least one phase of the battery electrode material unleached, wherein the acid has a pKa greater than or equal to −2. Either or both of the leachate and the remaining electrode material may then be regenerated (2806, 2808).

摘要： The present disclosure discloses a recycling method for a mixed waste material of lithium nickel manganese cobalt oxide (LNMCO) and lithium iron phosphate (LFP), including: conducting acid-leaching to obtain an acid-leaching liquor with nickel, cobalt, manganese, phosphorus, iron, and lithium; conducting adsorption separation with a resin, washing the resin with sulfuric acid to obtain a mixed solution of nickel sulfate, cobalt sulfate, and manganese sulfate, and subjecting the mixed solution to precipitation to obtain an LNMCO cathode material precursor; and subjecting an obtained solution with phosphorus, iron, and lithium to lithium precipitation to obtain a lithium salt precipitate, and subjecting a post-precipitation solution to concentration and electrospinning to obtain a ferric phosphate/carbon material. The process of the present disclosure can achieve comprehensive recycling of a mixed waste material of LNMCO and LFP and the directed circulation of waste LNMCO and LFP materials.

摘要： A process for recovering a nickel cobalt manganese hydroxide from recycled lithium-ion battery (LIB) material such as black mass, black powder, filter cake, or the like. The recycled LIB material is mixed with water and either sulfuric acid or hydrochloric acid at a pH less than 2. Cobalt, nickel, and manganese oxides from the recycled lithium-ion battery material dissolve into the acidic water with the reductive assistance of gaseous sulfur dioxide. Anode carbon is filtered from the acidic water, leaving the dissolved cobalt, nickel, and manganese oxides in a filtrate. The filtrate is mixed with aqueous sodium hydroxide at a pH greater than 8. Nickel cobalt manganese hydroxide precipitates from the filtrate. The nickel cobalt manganese hydroxide is filtered from the filtrate and dried. The filtrate may be treated ammonium fluoride or ammonium bifluoride to precipitate lithium fluoride from the filtrate. The composition ratio of nickel to cobalt to manganese in the acid filtrate may be adjusted to a desired ratio. The anode carbon is recovered and purified for reuse.

摘要： This invention relates to a new process for the extraction and elimination of deleterious material present in natural manganese dioxide (NMD), as well as in natural manganese dioxide obtained by such process. The process involves treating NMD with a HCl and water mixture in a reactor while stirring and heating the mixture. The heating temperature of the reactor is maintained in a predetermined range. The reactor is then fed with an amount of crushed NMD ore. A leaching reaction of said NMD ore with the HCl is produced by leaching for a period of time. Subsequently, the contents of the tank are filtered, washed and dried to recovery the concentrate of manganese dioxide substantially free of deleterious material.
