| description | The invention relates to a circulating type heap leaching gold extraction preparation technology, and relates to the technical field of heap leaching gold extraction. The circulating type heap leaching gold extraction preparation technology comprises the following steps that S1, ore is crushed through an ore crusher according to the ore density, and the crushed ore is filtered through a filter screen to accurately control the particle size of the ore; S2, the filtered ore is heaped to form an ore heap, and the permeability of the ore heap is checked; S3, a sodium cyanide solution is circularly sprayed to the top of the ore heap, and heap leaching is conducted for preset time; and S4, heap leaching liquid is collected to extract metal leached out of the ore; wherein when the sodium cyanide solution is sprayed to the ore heap, the solution concentration is set according to the obtained ore density P, when the solution concentration is set, the set solution concentration is adjusted according to the adjusted hea |
