Carbon Desorption1

Compared with similar products at home and abroad, this series of equipment has significant technical advantages, which are mainly reflected in:

1. High gold desorption rate: the carbon-poor gold grade after desorption is less than or equal to 50g/t (the same industry products are generally less than or equal to 100g/t).

2. High primary electrolysis rate: the average electrolysis rate of desorption solution is ≥90%. (The products in the same industry are generally around 70%).

3. Accurate gold balance: the actual amount of gold obtained after desorption and electrolysis is consistent with the theoretical gold content in the gold-loaded carbon. (Products in the same industry generally have the phenomenon of "floating gold or accumulative funds", which causes the loss of gold in the processing process and makes the amount of gold unbalanced)

4. Efficient and easy to operate: The whole set of equipment adopts integrated design, signal acquisition, operation adjustment control and safety protection are automated to ensure high efficiency, easy operation, safety and reliability during the entire operation period.

5. Low operating cost: The equipment is made of real materials of special materials (mainly including high-quality insulation materials, all-tetrafluoroethylene insulation materials, fully imported aerospace-grade circulating pumps, high-resistance electric shock heating pipes, etc.). The power-consuming equipment adopts frequency conversion design to ensure the low cost of operation and maintenance while ensuring the desorption electrolysis index.
