The device is mainly aimed at gold ore containing silver. After purification and deoxidation, zinc powder displacement device is added, and finally the gold mud is obtained.

Zinc Powder Displacement Device

Zinc powder displacement Process has 3 steps including pregnant Process purification, deoxidation and zinc powder filtering replacement.

1.Pregnant Process purification.

Principle:Gold pregnant Process often contains suspended solids which should be removed before replacement. Pregnant Process purification is the Process to remove suspended solid.Equipment:Frame press filter.

2.Deoxidation:Work Principle: Dissolved oxygen in pregnant Process hinders displacement of zinc and gold.Equipment:Deoxidation tower.

3.Displacement and filtering:Work principle: Including 2 steps adding zinc powder and displacement; when adding the zinc into pregnant Process, the displacement action starts. The displacement equipment finishes the displacement and gold mud filtration.Equipment: Zinc powder adding, Belt type zinc powder feeder, Disc type powder feeder, Zinc powder mixer.
