The extraction of the associated precious metals out of the construction industry's complex ores

The effective processing methods were investigated for the precious associated components extraction out of the ores by means of the physical and chemical and the chemical and metallurgical enrichment integration. It was established experimentally that the gold's disperse drops melted by means of the external heat source moved to the ore's surface through the pores under the thermocapillary pressure influence. After the enclosing rocks melted the gold drops were floated by the gas bubbles. The pyrometallurgical device was developed to extract the dispersive gold out of the complex ores in the course of the cast refractory materials processing.Ill.3. Ref. 5.
