Gold desorption electrolysis system

【Introduction】: A set of gold ore dressing equipment that obtains gold mud from gold-loaded carbon through desorption and electrowinning under high temperature and high pressure conditions.

【 Capacity 】: ≥3.5kg/t

【Improvement】: The high-efficiency and low-consumption fast desorption electrolysis system consists of a desorption column and an electrowinning cell.

Advantages

Under the conditions of high temperature (150℃) and high pressure (0.5MPa), the desorption rate can reach above 98%;

The desorption electrolysis temperature is the same, no heat exchange is required, and the power consumption is 1/4~1/2 of that of the conventional system due to the fast work;

The non-toxic desorption combination medicament contains carbon activator, which can regenerate the carbon, and the lean carbon does not need fire regeneration, which saves the cost of carbon regeneration;

Cyanide-free: no need to add sodium cyanide in the desorption solution, low cost and less pollution;

Gold mud is of high grade, no need for reverse electrolysis, easy to extract;

Safety: With triple safety protection measures, that is, the system's own intelligence, automatic pressure limiting and pressure release mechanism, and insurance safety valve.


Product Case

       In the 700tpd rock gold mine project in Zimbabwe undertaken by Xinhai, the mines are quartzite gold mines, mostly oxide ore or primary ore with low sulfur content. The beneficiation part combines the gravity separation + all-slime cyanide carbon slurry process, that is, the desorption electrolysis system for gold extraction. Extraction is efficient, fast, low consumption, low cost, and high production efficiency. This system has high grade of gold mud, does not need reverse electrolysis, and realizes efficient gold recovery.

Product Structure

        The desorption electrolysis system adds anions that are easily adsorbed by activated carbon to the desorption system, thereby replacing Au(CN)2- to achieve gold desorption. The precious liquid obtained by desorbing the gold-loaded carbon is recovered by the ionization method to obtain solid gold. Xinhai's high-efficiency, low-consumption and rapid desorption electrolysis device is mainly composed of two parts: desorption and electrolysis. The process of desorption and electrolysis is separated, so that the solvent is carried out in a comprehensive desorption tower, and the electrolysis of precious liquid is completed in a separate electrolytic cell. The four processes of desorption, precious liquid heating, solvent condensation and solvent recovery are centrally arranged 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 independent electrolytic cell through a pipeline for electrolysis to obtain crude gold , And then refined to obtain finished gold.
