ПРИМЕНЕНИЕ КОМБИНИРОВАННЫХ МЕТОДОВ В ПРОЦЕССЕ ИЗВЛЕЧЕНИЯ ДРАГОЦЕННЫХ МЕТАЛЛОВ ИЗ СЫРЬЯ УПОРНОГО СОСТАВА

This paper explores the hydrometallurgical treatment of complex gold-bearing pyrite-arsenopyrite ores and concentrates, highlighting a range of processing techniques along with their respective benefits and limitations. The discussed methods encompass conventional technologies, biooxidation, and selective leaching conducted at varying temperatures, typically followed by cyanidation. A common drawback among these approaches is the challenge of efficiently separating solid and liquid phases. Dehydration steps play a critical role in hydrometallurgical systems, as poor phase separation can negatively impact equipment performance and lead to higher energy demands. The authors propose strategies aimed at enhancing raw material utilization and improving overall process efficiency.
