Above-mentioned equipment was successfully developed by Changchun Gold Research Institute in 1998. It has possessed three patents and five monopolized technologies. Desorption solution does not contain sodium cyanide, it can reduce the grade of barren carbon down to 100g/t. The key technology of this equipment is that it can ensure the balance of metal quantity, and avoids gold- accumulating and gold- floating from the equipment, ensures the technological index steady and low cost of it. The content about technological advantages has been broadcasted by Xing Huo Science and Technology of CCTV. This technology was appointed as the energy-saving technology of gold production by National Development and Reform Committee in 2006, and was also appointed as standard equipment in the industry by National Development and Reform Committee in 2007, it passed the technique identifying in 2003, and won the second award of science and technology of China National gold Association, the entire technical level is advanced at home. This equipment has won three patent rights of China. The patent numbers of it are separately: 01241537.5 01241538.5 200620029209.1
