PRODUCTION LINE FOR YEAR-ROUND HEAP LEACHING OF PRECIOUS METALS Russian patent published in 2007 - IPC E21B43/28 

FIELD: mining industry, namely, geological and technological methods for enriching mineral resources.

SUBSTANCE: production line includes, mounted serially one after another: ore stack, draining system, reinforced concrete trough, trough board, free-flow pipeline, buffer vessel, receiving vessel, pump, force pipeline, irrigation system, device for precipitation of precious metals and device for additional strengthening of solutions. Production line is equipped with device for heating solution, mounted in front of irrigation system, free-flow pipeline, additional buffer vessel, additional receiving vessel, pump, force pipeline, emergency vessel, mounted successively one after another. Device for precipitation of precious metals and complex of devices for collecting and processing saturated solutions are positioned below boundary of seasonal freezing of soils. For operation in winter period, irrigation system is deepened into surface-adjacent layer of ore stack.

EFFECT: increased efficiency of industry operation due to year-round heap leaching of mineral resources under harsh climate conditions with little snow in winters and low negative temperatures.
