Analysis of factors influencing losses of recious metals during alluvial deposit exploitation

This article is dedicated to the analysis of factors influencing the losses of precious metals (e.g., gold) during the exploitation of alluvial deposits. Alluvial gold deposits represent one of the most common and significant sources of precious metals. Nevertheless, suboptimal mining methods, poor process organization, and other factors can lead to substantial losses of valuable metals. A review of existing methods and technologies for mining alluvial deposits was conducted to identify the primary sources of metal losses. Both technical and organizational aspects were analyzed, including the use of modern equipment, the efficiency of various exploration, enrichment, and gold extraction methods, as well as factors affecting process efficiency. The study revealed key factors contributing to the losses of precious metals, such as insufficient accuracy of geological exploration and ineffective methods of gold-bearing ore separation. Recommendations and methods to improve mining processes, reduce losses, and enhance overall efficiency in the extraction of precious metals were proposed.

Keywords: analysis, factors, losses, placer deposits, gold, organizational aspects, technologies, process efficiency, gold losses, innovation, optimization.
