Products with a substantial content of resinous-asphaltenic compounds were obtained by redox reaction of acid tar and asphalt of petroleum residue deasphaltization with propane and gasoline. Addition of their polycondensates with furfural to the charge makes it possible to produce finely porous carbon adsorbents characterized by higher selectivity in gold and silver extraction from multicomponent polymetallic solutions in comparison with industrial adsorbents.
