Process and Equipment

Zinc powder displacement process has 3 steps including pregnant solution purification, deoxidation and zinc powder filtering replacement

1. Pregnant solution purification

Principle: Gold pregnant solution often contains suspended solids which should be removed before replacement. Pregnant solution purification is the process to remove suspended solid.

Equipment:

  • Tube type filter

  • Frame purification tank

  • Frame press filter

2. Deoxidation

Work Principle: Dissolved oxygen in pregnant solution hinders displacement of zinc and gold

Equipment:

  •  Deoxidation tower

    Deoxidation tower

3.Displacement and filtering

Work principle:Including 2 steps adding zinc powder and displacement; when adding the zinc into pregnant solution, the displacement action starts. The displacement equipment finishes the displacement and gold mud filtration
