Technology for processing low-sulfide gold-quartz ore

The relevance of the research is caused by the necessity to acquire new knowledge about the enrichment of gold-bearing ores and the need to develop the resource base of the Russian Federation, namely involve subsoil use objects in economic circulation. The purpose of the study is to study the processing of low-sulfide gold-quartz ore using an integrated technology for the enrichment of mineral raw materials. The research methodology was based on the theoretical foundations of mineral processing, employing various methods including chemical, assay, thermal, spectrometric methods, atomic emission spectrometry, and others. The study of washability involved gravity and flotation enrichment techniques, specifically the GRG test and stage testing to optimize ore grinding conditions and enrichment stages. Results showed that gold recovery during the GRG test reached 72.75% with a total concentrate yield of 1.34%. This study contributes valuable insights into the efficient processing of low-sulfide gold-quartz ores, highlighting effective methods for enhancing gold recovery rates in current mining operations.
