Claims (2)

유지경화 후 수거되는 수첨니켈 폐촉매를 소각하고 소각된 잔사를 산침출 하는 소각침출공정, 산 침출된 것을 필터로 여과하여 여액은 용매추출공정으로 이동시키고 고상물은 수세 처리후 재첨출시켜 규조토를 재생시켜 주는 여과공정, 여과공정에서 생성된 여액을 인산계통의 산과 고급알콜류로 구성되는 유기용제에서 니켈을 제외한 기타 불순물을 추출제거 하고 순수니켈만을 잔액으로 남기는 용매추출공정, 용매추출공정에서 잔류한 잔사를 탄산니켈 등을 첨가하여 니켈을 결정추출하는 니켈추출공정으로 구성되는 유지경화용 니켈폐촉매에서 니켈과 규조토를 고순도로 회수하는 방법.Incineration leaching process to incinerate the hydrogenated nickel waste catalyst collected after oil-hardening, acid leaching the incinerated residue, and filter out the acid leaching with a filter to transfer the filtrate to the solvent extraction process and re-add the solids after washing with water. The filtrate produced by regeneration and the filtrate produced in the filtration process are extracted from organic solvents composed of phosphate acid and high alcohols. Other impurities except nickel are removed and the solvent is extracted from the solvent extraction process. A method for recovering nickel and diatomaceous earth with high purity from a nickel waste catalyst for maintenance hardening consisting of a nickel extraction process in which the residue is added to nickel carbonate to crystallize nickel. 제1항에 있어서, 유기용제가 포스핀산, 포스폰산 및 포스포르산과 같은 인산계 산중에서 어느 하나와 이소덴칸올, 이소옥틸알콜, 노닐페놀에서 선택한 화합물을 중량비로 5:1의 비로 혼합된 것을 특징으로 하는 방법.The organic solvent of claim 1, wherein any one of phosphoric acid acids such as phosphinic acid, phosphonic acid and phosphoric acid and a compound selected from isodencanol, isooctyl alcohol, and nonylphenol are mixed in a weight ratio of 5: 1. How to feature. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
