FIELD: metal extraction from gold-bearing cyanogen solutions by cementing. SUBSTANCE: device has a cementing installation in the form of a body with branch pipes for solution input and output and alternating cementing metal layers. Additionally it has layers of inert material, perforated plates fixed in the lower and upper body parts, and at least one more cementing installation in series with the first one enabling rearrangement with cementing metal and inert material layers to be alternated and compressed in a package with perforated plates, and inert layer is made of carbon material, e.g. graphitized fleecy jersey fabric. EFFECT: high efficiency. 2 dwg
