Abstract
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.
Highlights
The modern stage of mineral processing is characterized by the involvement of increasingly poorer and more difficult-to-concentrate ores in the technological process
Considering the fact that these attributes are most widely demonstrated in the technological properties of minerals [1], it can be assumed that this method must take its rightful place in a wide arsenal of physical and chemical methods of analysis used for assessing the behavior of minerals at different stages of technological processing of ores of various types of minerals
Analyzing the information available today, we can say that infrared spectroscopy can be widely used at various stages of studying the material composition of mineral raw materials while assessing its enrichment; and it can solve various tasks of technological ore processing
Summary
The modern stage of mineral processing is characterized by the involvement of increasingly poorer and more difficult-to-concentrate ores in the technological process. In this regard, there is a need for deeper study of their material composition at the level of recent advances in the field of crystal chemistry and crystal physics of minerals with the involvement of a wide range of the latest physical and chemical methods of analysis. Infrared spectroscopy (IR spectroscopy) has been widely used in recent years in the practice of geological exploration First of all, this is due to the high resolution of the method, its quickness, versatility and economy. Considering the fact that these attributes are most widely demonstrated in the technological properties of minerals [1], it can be assumed that this method must take its rightful place in a wide arsenal of physical and chemical methods of analysis used for assessing the behavior of minerals at different stages of technological processing of ores of various types of minerals
