We present the articles of the third issue of scientific journal "Mining Science and Technology” (Russia) for 2024:
“Invisible” gold is referred to submicroscopic gold particles that are 1–100 nm in size and are not detected using optical or electron microscopy. The presence of “invisible” gold and silver in ores complicates the selection of flow charts for their processing and owes the necessity for the development of new process solutions and improvement of existing ones. Experiments have shown the necessity of using magnetite to achieve coarsening fine silver particles. The optimal magnetite content is 10%, which leads to the formation of spherical aggregates of silver with a size of 20-40 microns. As a result of processing, it was possible to increase the particle size of precious metals up to 20-50 microns, which can then be extracted using traditional enrichment methods.
