Zinc powder replacement device
- Product Introduction: A system for extracting gold from precious liquid using zinc powder.
- Capacity: ≤1200m³/d
- Applications: This device is mainly used for gold ores containing a lot of silver. After purifying and deoxidizing the precious liquid, a zinc powder replacement device is added to finally obtain gold mud gold mining equipment.
- Product Improvements: The zinc powder replacement process consists of three operations: purification of your liquid, deoxidation and zinc powder filter press replacement.
Advantages and Features
- The spiral 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 zinc powder exposed to the air is small, which reduces the oxidation of zinc powder during use and improves the replacement effect.
Working Principle
The zinc powder replacement process is divided into three steps: purification of precious liquid, deoxidation and displacement filtration. 1. Principle of noble liquid purification: Gold-containing noble liquid often contains some suspended solids, which must be removed before replacement to avoid affecting the replacement effect and the quality of the gold mud. Purification of your liquid is the process of removing suspended solids. 2． Deoxidation principle: The dissolved oxygen in the precious liquid hinders the zinc replacement of gold. The oxygen in the precious liquid must be removed to ensure the smooth progress of zinc replacement of gold. 3. Principle of displacement filtration: It includes two operations: zinc powder addition and replacement. When zinc powder is added to the precious liquid, the displacement reaction begins, and the displacement equipment completes the final displacement and filtration of gold mud.

Case Study
During the cyanidation process in a gold mine, part of the copper and lead 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, causing a sharp decrease in the gold replacement rate and seriously affecting production indicators. In response to these problems, the second series separately introduced Huston zinc powder replacement device. The zinc powder replacement reaction effect is obvious, the replacement rate is increased, and accordingly, the production efficiency is also improved.
