STUDY ON SPRAY IRRIGATION OF HEAP LEACHING

The leaching solvent irrigation is one of the very important part of heap leaching. A new way of spray irrigation is introduced in this paper. The heap was simulated with uranium ore, more uranium average concentration and more leaching rate were got by the condition experiment of spray irrigation, less time was used during the leaching, and more economic benefits were obtained. The parameter will provide the reference basis for the mine to use the spray irrigation.
