FIELD: metallurgy.
SUBSTANCE: extraction line of precious metals from cyanide solutions and/or pulps as per a coal-absorption technology includes a plant for metal sorption from solutions and/or pulps, a plant of secondary metal concentration, a plant for metal desorption and a plant of electrolytic metal extraction, which are installed in the technological process flow and connected to each other via transport pipelines. In addition, the line includes the plant for secondary metal concentration, which is arranged before the metal desorption plant. Besides, the secondary metal concentration plant with a pipeline of rich eluate is connected to the outlet as to eluate of the metal desorption plant, and with the coal feeding system it is connected to the input as to coal of the metal desorption plant. The metal desorption plant is connected through the plant for electrolytic metal extraction to the plant for secondary metal concentration with a transportation pipeline of poor eluates, and with a waste coal transportation pipeline it is connected to the plant for metal sorption from solutions and/or pulps.
EFFECT: improving efficiency of the line at simultaneous reduction of power consumption.
