| With the increased demand to gold in the world, the gold production is increased steadily, bringing, however, a much more serious environmental pollution to the human beings. The researchers undertaking gold extraction showed a great concern to this situation, studying methods of treatment and developing the new technologies with no or little pollution to promote the application of clean gold extraction technology. To promote the development of the clean gold extraction technology, this paper described the domestic situation of gold extraction and putting environment under control, and progresses in the research on gold extraction without cynide, both at home and abroad. |
