Zinc Powder Displacement Device

Advantages

The screw feeding is uniform and continuous, which solves the difficulty of adjusting the amount of zinc powder added by traditional machinery and the problem of uneven adding amount, and reduces the content of residual zinc, which not only reduces the production cost, but also improves the smelting effect;

The area of the zinc powder exposed to the air is small, which reduces the oxidation of the zinc powder during use and improves the replacement effect.

working principle

1．Pregnant solution purification: Gold pregnant solution often contains suspended solids which should be removed before replacement. Pregnant solution purification is the process to remove suspended solids.

2．Deoxidation: Dissolved oxygen in pregnant solution hinders displacement of zinc and gold.

3．Displacement and filtering: Including 2 steps adding zinc powder and displacement; when adding the zinc into pregnant solution, the displacement action starts. The displacement equipment finishes the displacement and gold mud filtration.

technical parameter

success case

In the cyanidation process of a gold mine, some copper and lead were dissolved and a large amount of sodium cyanide was consumed, resulting in an increase in the concentration of copper, lead and zinc in the precious liquid, a sharp drop in the replacement rate of gold, and a serious impact on production indicators. In response to these problems, Xinhai zinc powder replacement device was introduced separately for the second series, and the zinc powder replacement reaction effect was obvious, the replacement rate was improved, and the production efficiency was also improved accordingly.
