Carbon adsorbents with mechanical strengths of 90-93% and a micropore volume of 0.16-0.3 cm3/cm3 have been obtained from nitrated asphaltites by the existing industrial technology. Compared to industrial carbon with the trademark KAD-iodine, medium-charred specimens are highly selective in extracting gold and silver from multicomponent polymetal solutions and have a high capacity for sorbing arsenic from waste waters.

Notes
The study of sorptivity with respect to noble metals and arsenic was performed by A. I. Gorbovskii in the laboratory at the Kochkanarsky plant.
