DEVICE FOR LEACHING OF PRECIOUS METALS

摘要

FIELD: metallurgy.;SUBSTANCE: device for precious metals leaching includes a conic reactor with a lid, junction pipes for inlet and outlet of a reaction mixture, a node for force circulation consisting of a pump and connecting pipes. The node for force circulation is provided with an ejector connected to the lower part of the conic reactor. At that the ejector nozzle is connected to the outlet of the circulating pump, the ejector suction chamber is designed with a channel connecting it to an internal volume of the reactor, and the ejector diffuser is connected to a junction pipe of the reaction mixture inlet to the reactor. The junction pipe of the reaction mixture inlet is located tangentially in an upper part of the reactor, and the junction pipe of the reaction mixture outlet is located in the centre of the reactor lid, it is submerged in the reaction mixture and is connected to the circulating pump inlet.;EFFECT: increasing the speed of precious metals leaching.;1 dwg, 1 tbl
