(1) Vigorously improve the technical level of gold mining and smelting.
Due to the large proportion of difficult gold ore reserves in China's proven gold reserves, and the associated gold reserves are also considerable, it is necessary to further organize technical research, increase R&D investment, increase the recovery rate of gold, and improve mining and metallurgy technology. The angle guarantees the sustainable development of gold production.
(2) Actively study new processes and new methods, make full use of low-grade refractory gold mines, and improve resource utilization efficiency.
In the 21st century, the rapid development of science and technology, the application of gold smelting technology development, while improving the quality of gold smelting, but also to better play the economic and social benefits of the environment. We must strengthen the research on gold smelting technology and actively introduce foreign advanced smelting technology to meet the development needs of China's gold market, but also to pave the way for its future development.
While using conventional smelting technology, it is necessary to speed up the development including biological treatment technology, pressurized oxidation pretreatment technology, improve gold recovery rate and reduce environmental pollution.
(3) Research and application of non-cyanide gold immersion reagents.
Cyanide leaching is slow due to cyanide leaching, and the leaching process is easily interfered by impurities such as arsenic and sulfur; the toxicity is high, the environmental protection cost of the mine is large, and it is harmful to the ecological environment; the fine grain is wrapped with gold, high arsenic, high sulfur, and organic The problem of direct leaching of refractory gold ore from charcoal is very poor, and sometimes the gold extraction effect is unsatisfactory. The development and application of non-toxic and non-polluting gold extraction technology will become the focus of future research.
Non-cyanide gold leaching reagents include thiourea, thiosulfate, thiocyanate, polysulfide and stone sulphur, halogen and its compounds.
