In gold electrowinning process,when the electrolysis equipment is added with anions that 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, pregnant solution processes the via ionization. At last, the solid gold is attained.
Yantai Rhyther Mining Machinery Co.,Ltd. is a professional manufacturer of gold desorption and electrowinning equipment in China. They are high temperature, high pressure, no cyanide, auto control of desorption with features of high efficiency, low consumption and rapid.
Solvent Desorption. The desorption liquid and the gold loaded carbon in the process of electrowinning of gold are respectively placed in different mass transfer layers in the comprehensive desorption tower, that is, the pregnant liquid is concentrated in the lower part of the comprehensive desorption tower, and the gold loaded carbon is placed ...
Gold Sludge Production Carbon Desorption and Electrowinning Facilities 1.1 Elution CN or OH dissolved in desorption solution is easier than Au2 to be absorbed by the activated carbon which causes Au2 absorbed on loaded carbon is replace by CN or OH and the reversible balance of of gold adsorption is broken.
Desorption Electrolytic EquipmentOur desorption electrolysis unit is a new style high efficiency product, integrated with new technique and technology.

Desorption does not require sodium cyanide, which reduces cost and averts pollution. Work Principle 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.
