chapter 1 introduction to electrolysis, electrolysers and

A concept called the “hydrogen economy” based on a H 2 energy system was put forward in the 1970s in which hydrogen was proposed as the major energy vector. 3 In practice this could mean that water is used to generate hydrogen and oxygen by, for example, electrolysis, which are able to be used in fuel cells to generate power. Thus, we have

High Efficiency: When the grade of gold loaded carbon reaches 3000g/t, desorption rate can reach more than 96%. Fast: Due to the high temperature and pressure, the time of desorption electrolysis is 12 hours shortened by 50-70%. Low energy consumption: Due to the same temperature and fast working, the energy consumption is 1/2-1/4 of regular system

high temperature pressure gold electrolysis

Desorption electrolysis system process. In gold electrowinning process, when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, Au(CN)2ˉ is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, the pregnant solution is processed via ionization
