To address the world-class challenge of processing fine-grained refractory gold ores high in arsenic, sulfur, and carbon in the Shuiniudong Gold Mine, Guizhou Zijin successfully developed the first set of pressure oxidation equipment in China, enabling solid-liquid-gas three-phase reactions under high temperature, high pressure and high acid conditions. The internationally leading technology is the first in China’s gold industry.
The debottlenecking and expansion projects of the Shuiniudong Gold Mine and the Bojitian Gold Mine are progressing at an accelerated pace. The 1Ktpd pressure oxidation project is scheduled to be completed in 2023, and the 4 Ktpd processing project is undergoing preliminary preparations with the goal of completion in 2024.
