Data for: Recovery of rare earth elements from electronic waste

This dataset contains information regarding the patented methods and uses (both application and granted patents) for the recovery of rare earth elements from electronic waste. The following databases used have been used for data mining: - Espacenet (a free of charge database provided by the European Patent Office), accessed on Oct. 25, 2021 - Orbit Intelligence (FamPat) (a fee-based database provided by Questel), accessed on Oct. 25, 2021 The file titled “Rare earth recover_Espacenet” contains information related to Title, Inventors, Applicants, Publication number, Earliest priority, IPC, CPC, Publication date, Earliest publication, and Family number. The file titled “Rare earth recover_Orbit” contains information related to Priority numbers, Application numbers, Publication numbers, Priority dates, Application dates, Publication dates, Title, Abstract, Current assignees, Claims. The patent searches were carried out by keywords and classification codes. Both IPC (International Patent Classification) and CPC (Cooperative Patent Classification) codes were used. Value of the dataset: prior art searches, technological trends Definition of the classification codes used Y02W 30/82: Recycling of waste of electrical or electronic equipment [WEEE] C22B 59/00: Obtaining rare earth metals C01F 17/00: Compounds of rare earth metals H01F 1/053: Magnets containing rare earth metals H01F 1/15325: containing rare earth Y02P 10/20: Recycling Y02W 30/50: Reuse, recycling, or recovery technologies本数据集收录了从电子废弃物中回收稀土元素的专利方法与应用相关信息，涵盖专利申请与授权专利两类。 本次数据挖掘所用数据库如下： 1. 欧洲专利局（European Patent Office）提供的免费数据库Espacenet，检索日期为2021年10月25日 2.
