Accurate gold balance gold desorption electrolysis machine

Accurate gold balance Gold Desorption electrolysis machine was developed by Changchun Gold Research Institute Co., Ltd. in 1998 and entered the market. It has been used in more than 800 enterprises at home and abroad. This series of equipment is oriented to the gold-loaded carbon in the gold cyanide carbon slurry process for gold desorption and electrolysis, and the gold adsorbed on the gold-loaded carbon is produced in the form of high-grade gold mud. After decades of practical application and continuous optimization and improvement in enterprises, this series of equipment has developed to the fifth generation.

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.

This series of equipment has 3 patented technologies and 5 proprietary technologies. Sodium cyanide is not used in the desorption liquid, which reduces the lean carbon grade below 100g/t. The key technology of this equipment is to ensure the balance of metal content, avoid the phenomenon of equipment "accumulation" and "floating gold", and ensure the stable and stable technical indicators of the equipment. The cost is low, and the content of technological advancement has been broadcast on the Spark Science and Technology column of CCTV in 2000. The technology passed the technical appraisal in 2003 and won the second prize of Science and Technology of the China Gold Association. The overall technical level is domestically leading. In 2006, it was designated as an energy-saving technology for gold production by the National Development and Reform Commission. In 2007, it was designated as an industry standard equipment by the National Development and Reform Commission. The equipment has obtained 3 Chinese patents, the patent numbers are: 01241537.5 01241538.5 200620029209.1
