Introduction:A system extracts gold from pregnant solution by zinc powder.
Improvement:Zinc powder displacement process is composed of pregnant solution purification, deoxidation and zinc powder filtering replacementAdvantages:
Spiral zinc powder feeder is a kind of zinc powder feeding machine newly developed by Xinhai with the following advantages.
With even and continuous spiral feeding, it has solved the problems of difficulty in adjusting zinc powder feeding amount in traditional machinery and uneven feeding amount, and reduced the residual zinc content, which not only reduces the production costs, but also improves the smelting effects.
With small area of zinc exposure in the air, the oxidation of the zinc powder is reduced in the operation, and the replacement effect is improved.Technical Parameters:
