The Heap Leaching Technology and Production Practice of the Huayagou Low-grade Gold Ores

The exploitation of low-grade mines is an important part in the gold production. The satisfactory production efficiency is obtained during the course of heap leaching of Huayagou low-grade gold ores. The techno-economic index of gold production by the heap leaching technology already came to advanced or leading level in China, and several indexes are near to level of developed countries. This technique opened up a suitable development way for exploitation of low-grade gold ores.
