PRODUCTION LINE OF FLOTATION CONCENTRATES Russian patent published in 1997 - IPC

FIELD: hydraulic metallurgy of noble metals, production line for gold and silver extraction from sulfide flotation concentrates using thiocarbamide process, that provides for mounted in direction of production process and linked to each other by transportation means concentrate comminution module, agitated lixiviation module, electrolytic precipitation module and demetallized solution purification and conditioning module. SUBSTANCE: production line has filtration lixiviation module, that is mounted after comminution module, and filtration lixiviation solutions electrolysis module located before electrolytic precipitation module. In the case filtration lixiviation solutions electrolysis module using means of concentrate transportation is linked with comminution module and using transportation means of filtration lixiviation sludge it is linked with agitated lixiviation module and using pipelines of demetallized solution and filtrate it is linked with electrolysis module. Electrolysis module through electrolytic precipitation module is linked with transportation pipeline demetallized solution purification and conditioning module, that using transportation pipeline is linked with agitated lixiviation module, and the latter through pipeline of poor silver-bearing solutions is linked with filtration lixiviation module. EFFECT: increased productivity. 6 cl, 6 dwg
