I. Gold Processing Equipment 1: Zinc Powder Displacement Device Zinc powder displacement process includes three stages: purification of pregnant solution, deoxidation and displacement filtration. The suspended substance in the gold-bearing pregnant solution is removed by purification stage. The dissolved oxygen in the pregnant solution has an obstructive effect on the gold recovery by zinc displacement, so the oxygen in the pregnant solution must be removed to ensure the smooth progress of gold recovery. The displacement filtration stage includes zinc powder addition and displacement operation. The displacement reaction starts once the zinc powder is added into the pregnant solution. And the final displacement and filtration of gold mud are completed by the displacement device. Therefore, zinc powder displacement device mainly includes deoxygenation tower, zinc powder feeder and displacement device. Here are some points we should notice when operate the zinc ...
