稀土金属二次回收再利用研究综述

稀土金属广泛应用于冶金、石油化工、玻璃陶瓷等领域，是当代高科技新材料（永磁材料、抛光材料、催化材料等）的重要组成部分。长期以来，中国稀土的高产量致使国际上普遍认为中国垄断了全球稀土金属生产和精炼供给，导致进口国面临着严重的供给风险，纷纷展开了稀土金属二次回收再利用的研究。本文概述了全球范围内稀土元素回收的当前和未来潜力，主要研究了从最终报废产品、生产过程中的工业废料、含稀土元素的工业固、液废弃物三方面回收稀土元素的研究现状以及未来回收潜力。 

A Review on Recycling and Reuse of Rare Earth Metals

Rare earth metals are widely used in metallurgy, petrochemical industry, glass ceramics and other fields, they are important components of modern high-tech new materials (permanent magnet materials, polishing materials, catalytic materials, etc.). The high output of rare earth in China has led the international community to generally believe that China has monopolized the global production and refining supply of rare earth metals, which has led to serious supply risks for importing countries. Therefore, research on recovery and reuse of rare earth metals has been carried out one after another. This paper reviews the current and future potential of rare earth element recovery. And mainly includes recovery of rare earth metals from scrap products, industrial waste in production process, industrial solid and liquid waste containing rare earth elements.
