DEVICE TO DETERMINE TECHNOLOGICAL PARAMETERS OF HEAP METAL LEACHING FROM ORE AND GEO-TECHNOGENIC WASTE IN COLD AND WARM SEASONS Russian patent published in 2006 - IPC E21B43/28 

FIELD: dissolving minerals other than hydrocarbons, for instance by an alkaline or acid leaching agent and physical and chemical permafrost rock erosion investigation.

SUBSTANCE: device comprises ground tray, supply vessel, supply chamber, cooling chamber adapted to receive round tray. The ground tray is formed as transformer consisted of extensible telescopic pipes connected with each other in tray joints by hinges. The telescopic pipes may rotate through 360° about hinge axes. The ground tray is installed on platform fastened to frame by means of hinge located from one side and by means of lifting jack arranged from another side thereof. The device also comprises thermocouple array, thermistor array and measuring capillary pipes. Metal contour with heat emitter is installed inside cooling chamber over ground tray. The heat emitter is arranged on electric motor provided with driving gear. Supply vessel is made as thermostat. Supply chamber is made as hydrometric pipe for metered solution distribution into ore spraying system.

EFFECT: possibility to investigate technological leaching parameters in ground tray having different shape and lithologic structure with taking into consideration tray inclination and orientation change, which varies heat transmitted from outer sources, namely sun and solution, and from inner sources, which generate heat due to physical and chemical metal leaching reactions.
