Zinc powder replacement is a process in which gold-containing precious liquid is treated after cyanide leaching and zinc powder is used as a reducing agent to replace gold and silver from the leachate.
【Processing Capacity】:≤1200m³/d(Based on the actual processing capacity of the manufacturer)
【Application Scope】：It is mainly suitable for processing gold minerals containing more silver. After purifying and deoxidizing the precious liquid, a zinc powder replacement device is added to obtain qualified gold mud.

Click to add WeChatIn the zinc powder replacement process, the spiral feeding is uniform and continuous, which improves the problem of difficulty and uneven adjustment of the amount of mechanical zinc powder added by traditional machines, reduces the content of residual zinc and production costs, and effectively 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.
The zinc powder replacement system mainly consists of your liquid storage tank, clarification tank, deoxidation tower, hydraulic jet pump, water pump, pool, zinc powder feeder, zinc powder mixer, water seal pump, plate It is composed of frame filter press, lean liquid tank and other parts.
The zinc powder replacement system is mainly divided into three steps: purification of your liquid, deoxidation and replacement filtration.
Your liquid purification:Gold-containing precious liquid often contains some suspended solids, which must be removed before replacement to avoid affecting the replacement effect and gold mud quality. Purification of your liquid is the process of removing suspended solids.
deoxidation:The dissolved oxygen in the precious liquid hinders the zinc replacement of gold, and the oxygen in the precious liquid must be removed to ensure the smooth progress of zinc replacement of gold.
Displacement filtering:It includes two parts: zinc powder addition and replacement. Zinc powder is used to replace the precious metals in the precious liquid (leaching liquid) to form gold (silver) mud.
