FIELD: hydrometallurgy of noble metals, namely, gold recovery from ores by cyaniding, for example, at processing ores with non-industrial content of gold. SUBSTANCE: line comprises mounted according to technological process and mutually connected by transportation means disintegrating module, module for dewatering of disintegrated products, module for sorption cyaniding of concentrated products, module for desorption of gold from saturated sorbent, module for regeneration of sorbent, module for demetallization of gold-containing solutions and tailings dump jointed with module for sorption cyaniding by means of transporting clarified liquid phase for percolation leaching and by means for transporting solutions of percolation leaching with the module for sorption cyaniding and/or the module for disintegration. EFFECT: enlarged functional possibilities of the line due to provision of processing lean ores by their percolation leaching in separate cycle by clarified solution of tailing pulp and processing of productive solution of percolation leaching in common cycle. |
