Abstract
The authors determine the forms of gold transfer under coal combustion by using the experimental data. It is found that the micron-sized and nano-sized gold particles are carried away with flue ash during combustion, and only the insignificant part of the gold, localized at underburnings, remains in the form of the free gold within a combustion chamber. The authors shows that applying the method of fumesteam mixing and its futher condensation provides the maximum volatile forms of gold, being the base for creating the geotechnology of unified production cycle of the efficient stock usage and the environmental safety provision.
