To study the process of extracting the gold contained in the solution by passing the gold metal from the obsolete electrical equipment into the solution. Acces.Currently, not only in Uzbekistan, but all over the world, there is a decrease in the base of ores and minerals for the extraction and production of non-ferrous, rare, scattered and rare metals, and the increase in the amount of waste, not only man-made secondary used useless electrical equipment, and as a result, the ecological balance 'change, it can be seen that it affects the climate changes as well. Taking these into account, man-made waste of production containing rare and rare metals, unusable electrical equipment, and waste processing are of particular importance. In this regard, it is of particular importance to determine the methods of processing mineral and secondary raw materials, to create technology for extracting non-ferrous and rare metals from the dust of metallurgical plants, and to develop resource-saving technology, as well as to improve and introduce existing technologies.
