Review highlights analytical methods for accurately determining gold and rare earth metals in ores, suggesting non-destructive techniques may improve extraction processes.
The review examines the prospects for involvement in the processing of gold-bearing and rare earth metal ores that are considered to be strategic mineral resources. It provides information about the mineral resource base of gold and describes the mineral formations and associations of gold in these ores. The article also provides information on the state of the mineral resource base for rare earth metals, including scandium, based on data from published sources such as the journals "Mining Industry" and "Gold and Technology". Due to the complex nature of these ores and their low content of valuable components, obtaining accurate analytical data can be challenging. However, the review discusses modern analytical methods that can help accurately determine the concentration of strategic metals in these ore objects. The method of instrumental neutron activation analysis (INAA), which belongs to the group of non-destructive methods, provides the analysis of representative samples and is characterized by high accuracy (correctness) of definitions, is considered in detail. The article presents the nuclear physical characteristics of the elements often determined by this method. Examples of the determination of Au, Sc, and rare earth elements (REE) in ore samples and waste materials using the INAA technique with a Californium neutron source are given.
