Аннотация: | Gold in sulfide ores and technogenic formations after their processing is concentrated in the form of micro-dispersed particles. This article presents a study on the composition of the ultrafine gold particles, their size distribution, and some predicted gold properties. The studies were carried out using copper pyrite ore as an example. It was found that the content of metallic impurities in Au particles, which may appear during their formation under natural conditions, increases with a decrease in their size. The presence of copper in gold particles significantly lowers the melting point of the alloy. The data obtained are used to develop a technology for utilizing gold from technogenic formations of a similar type. |
