Infrared spectroscopy (IR) is a highly effective method for the analysis of minerals, rocks and ores, capable of solving a whole range of problems when choosing innovative solutions for the technological processing of various types of mineral raw materials. The article considers the main directions of using the infrared spectroscopy method in assessing the technological properties of minerals and their behavior in technological processes: evaluation of the grade (quality) of mineral raw materials; analysis of the behavior of minerals in the technological process with prediction of their technological properties; analysis of changes in the structure and properties of minerals in technological processes; operational analysis of mineral substances at various stages of technological processing. The article illustrates all aspects of the use of infrared spectroscopy at various stages of studying the material composition of mineral raw materials in its enrichment assessment by specific examples of solving problems arising from the technological redistribution of various types of ore and non-metallic minerals.

Приведены результаты изучения спектров ЭПР и термолюминесценции апатита Ковдорского месторождения. Установлена их связь с выделенными морфоструктурно-конституционными разновидностями минерала. Выявлены закономерности изменения интенсивности линии поглощения парамагнитного центра F – -O – -F – в контуре месторождения – как одной из высокочувствительных конституционных характеристик минерала. Определены особенности взаимосвязи кристаллохимической эволюции апатита с основными этапами и стадиями формирования рудного комплекса месторождения.
Стадіальний аналіз на рівні рудне тіло - агрегат - індивід дозволив виявити і охарактеризувати стадії сингенезу, діагенезу і метаморфізму малозалізистих руд Ковдорского родовища. Виявлено узгоджена, односпрямована еволюція магнетиту, апатиту і бадделеіту в чіткому зв'язку з просторово-часовою мінливістю процесів рудоутворення на родовищі. Зазначені особливості онтогенії асоціації магнетит-апатит-бадделеїт можуть служити досить надійною мінералого-генетичною основою для проведення геолого-технологічного картування малозалізистих руд родовища.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
