| description | The development of modern technologies for the complex extraction of valuable components from refractory ores and technogenic deposits is possible on the basis of the latest achievements of fundamental sciences, a combination of physicochemical, enrichment and metallurgical processes. The paper describes the results on the impact of laser radiation on mineral samples with ultrafine «non-recoverable» gold from silt ponds-settlers of alluvial deposits in the Far East. The object of research is the impact of a source of continuous laser radiation on samples of minerals, objects of alluvial deposits containing submetric and nanosized forms of gold that are not recoverable by traditional gravity methods. The purpose of this work was to study the processes of interaction of laser radiation with dispersed mineral media containing ultrafine gold and to determine the conditions for agglomeration of ultrafine gold. Electron microscopic images of the samples were obtained using a LEO EVO 40HV microscope (Carl Zeiss, Germany) equipped with an INCA-ENERGY energy-dispersive analyzer. A model is proposed that describes the processes at the boundary of heterogeneous phases. An analysis of the discovered effect of gold agglomeration made it possible to formulate technical solutions that were reflected in patents for inventions. The discovered effect of gold agglomeration made it possible to find technical solutions in the form of patents for inventions. |
