SORPTION APPARATUS Russian patent published in 2019 - IPC C22B3/02 B01D15/04 

FIELD: technological processes.

SUBSTANCE: invention relates to devices for sorption extraction of useful components from solutions and pulps and can be used in hydrometallurgy of rare, non-ferrous and noble metals. Sorption apparatus comprises a housing, an air-lift, a circulator, a disperser, branch pipes for feeding and discharging pulp or solution, as well as a sorbent, a drain located below the pulp level. Drainage is made in the form of a submersible drainage device with a converging bottom and with a drain tube, providing removal from the apparatus by gravity of pulp or solution. Disperser is located inside the circulator and is connected to the compressed air feed branch pipe and is made in the form of a perforated pipe on the outer surface of which elastic elements are arranged.

EFFECT: disclosed design allows for continuous process of sorption from solution or pulp to improve reliability of device, simplify its maintenance, reduce operating costs by reducing losses of expensive sorbent.
