FLOW LINE FOR PROCESSING OF METALLIFEROUS RAW MATERIALS OF GOLD-BEARING DEPOSITS Russian patent published in 1999 - IPC

FIELD: recovery of gold; flow lines for processing of metalliferous raw materials of gold-bearing deposits. SUBSTANCE: flow line includes successively connected: device for disintegration and particle size classification, device for obtaining of heavy metal concentrate, receiving bin, immersion pump for handling concentrate, magnetic separator, device for mercury sublimation with closed cycle, and device for smelting of gold with mixture. The flow line is additionally provided with a device for classification and concentration of fine material in thin water flow with continuous withdrawal of concentrate and device for separation of gold-containing amalgam. Devices are installed successively after device for obtaining of heavy metals concentrate. The flow line is also provided with device for material drying, triboadhesion separator successively connected with each other and installed between magnetic separator and device for mercury sublimation in closed cycle. Device for smelting of gold with mixture is additionally supplied with absorber from natural mineral fillers, for instance, zeolite-containing tuffs. The absorber is installed at outlet of gas-discharging branch pipes of heating furnace. Device for separation of gold-containing amalgam is additionally provided with DC activator. EFFECT: higher rate of gold recovery and ecological safety, mobility of devices comprising flow line. 3 cl, 2 dwg
