Carbonic sorbents obtaining out of molding powders based on thermosetting resin with the usage of super-high frequency energy

Development of pulp countercurrent processes of the noble metals extraction requires a great quantity of high-strength active carbonic sorbent. Produced during last years the carbonic sorbents based on phenol-formaldehyde resin (PFR) and their derivatives with the reasonable indexes of strength and sorbent activity are very expensive and as a result they don't gain a wide ground. To reduce the expenses for the production of the carbonic sorbents based on PFR it is suggested to use the energy of super-high frequency.
