Compared with other methods of cyanide gold extraction, heap leaching method has its own characteristics, which can be characterized by mine resources, basic construction characteristics, production process characteristics and production cost characteristics.

1. Characteristics of mine resources The heap leaching method is used to recover gold-bearing ore and old tailings that cannot be used or abandoned, and the geological work of heap leaching ore resources is generally low. The degree of oxidation and structure of ore produced by heap leaching There are certain requirements for the associated elements and the state of occurrence of gold.
2. Basic construction features The construction of the basic construction of the gold-leaching method is relatively small, the infrastructure construction period is short, and the effect is quick. The construction of domestic heap-dip production mines is gradually built and developed through the combination of exploration and construction.
3. Characteristics of production process The heap leaching method is simple in production and flexible, and its production process is intermittent and batch. Production is mostly in the open air and is greatly affected by the weather. The recovery rate of gold is low. Due to the large size of the ore, the amount of residual cyanide is small, easy to disinfect and meet environmental requirements.
4. Production cost characteristics The low production cost of heap leaching gold extraction is an important factor for the vigorous vigor of heap leaching production, so there is still some profit in handling low grade raw ore.
