Category: Gold Processing Equipment
High efficiency, low consumption and rapid desorption electrolysis system
- Product Introduction: A set of gold mineral processing equipment that obtains gold mud from gold-loaded carbon through desorption and electrowinning under high temperature and high pressure conditions.
- Capacity: ≥3.5kg/t
- Applications: Used in cyanide alchemy to extract solid gold from gold-loaded carbon.
- Product Improvements: The high-efficiency, low-consumption rapid desorption electrolysis system consists of a desorption column and an electrowinning cell.
Advantages and Features
- Under the conditions of high temperature (150°C) and high pressure (0.5MPa), the desorption rate reaches more than 98%
- the desorption and electrolysis temperature is the same, no heat exchange is required, and due to the fast operation, the power consumption is 1/4 to 1/2 of the conventional system
- the non-toxic desorption combination agent contains carbon activator, which regenerates the carbon, and the lean carbon does not need to be regenerated by fire, saving the cost of carbon regeneration
- cyanide-free: no sodium cyanide is added to the desorption solution, low cost and no pollution
- The gold mud is of high grade, does not require reverse electrolysis, and is easy to extract
- Safety: It has triple safety protection measures, namely the system’s own intelligence, automatic pressure-limiting pressure release mechanism, and insurance safety valve.
Working Principle
Desorption electrolysis system: Add anions that are easily adsorbed by activated carbon into the desorption system to replace Au(CN)2- and achieve gold desorption. The precious liquid obtained by desorbing gold-loaded carbon is recovered through ionization method, thereby obtaining solid gold. Huston’s high-efficiency, low-consumption rapid desorption electrolysis device is mainly composed of two parts: desorption and electrolysis. The processes of desorption and electrolysis are separated, so that the solvent is carried out in a comprehensive desorption tower, and the expensive liquid electrolysis is completed in an independent electrolytic cell. The solvent desorption and expensive liquid addition The four processes of heat, solvent condensation and solvent recovery are centralized in the comprehensive desorption tower, and the precious liquid obtained after the solvent vapor is desorbed from the gold-loaded carbon is introduced into an independently installed electrolytic cell through a pipeline for electrolysis to obtain crude gold, which is then purified to obtain finished gold.

Case Study
In the Zimbabwe 700t/d rock gold mine project undertaken by Huston, the mine is a quartzite gold mine, mostly oxidized ore or primary ore with low sulfur content. The mineral processing part combines the gravity separation + all-mud cyanide carbon slurry process, that is, the desorption electrolysis system to extract gold. The extraction is efficient, fast, low consumption, low cost and high production efficiency. This system has high gold mud grade, does not require reverse electrolysis, and achieves efficient recovery of gold.
