Abstract

Abstract Domestic and world tendencies of involvement in the processing of ores of rare metals (RMs) and rare-earth metals (REMs) are shown. It is shown that the main direction of innovative activity is the development and application of modern breakthrough technologies for complex processing of mineral raw materials with the production of high-quality products while minimizing environmental damage. The main deposits of rare and rare-earth metals are systematized from the standpoint of the content of the main components, concentrator minerals and the main enrichment methods. The main principal technological schemes of processing of some deposits of RMs and REMs in Russia (Lovozer, Tomtor, and Afrikand deposits) are given. Options for involving technogenic and off-balance raw materials in the processing in order to extract strategic metals are considered. It is substantiated that innovative environmentally friendly processes for the extraction of rare and rare-earth metals from complex ores of complex material composition are being actively developed in Russia at present.

从复杂矿石中提取稀有和稀土元素的创新环保安全工艺

摘要介绍了国内外稀土金属和稀有金属矿石加工的发展趋势。研究表明，创新活动的主要方向是开发和应用现代突破性技术，以生产高质量的产品，同时尽量减少对环境的破坏。从稀土金属的主要成分含量、富集矿物和主要富集方法等方面对稀土金属的主要矿床进行了系统的分类。给出了处理俄罗斯一些稀土和稀土矿床(Lovozer、Tomtor和Afrikand矿床)的主要技术方案。考虑在加工过程中使用技术性和不平衡的原材料以提取战略金属的各种选择。有证据表明，目前俄罗斯正在积极开发从复杂材料组成的复杂矿石中提取稀有和稀土金属的创新的无害环境工艺。

期刊介绍： Geology of Ore Deposits is a periodical covering the topic of metallic and nonmetallic mineral deposits, their formation conditions, and spatial and temporal distribution. The journal publishes original scientific articles and reviews on a wide range of problems in theoretical and applied geology. The journal focuses on the following problems: deep geological structure and geodynamic environment of ore formation; distribution pattern of metallogenic zones and mineral deposits; geology and formation environment of large and unique metallic and nonmetallic deposits; mineralogy of metallic and nonmetallic deposits; physicochemical and isotopic characteristics and geochemical environment of ore deposition; evolution of ore-forming systems; radiogeology and radioecology, economic problems in exploring, developing, and mining of ore commodities.
