A system extracts gold from pregnant solution by zinc powder.
Zinc powder displacement process is composed of pregnant solution purification, deoxidation and zinc powder filtering replacement.
Pregnant solution storage pool Settle tank Deoxygenation tower Hydraulic jet pump Water pump Water tank Zinc powder feeder Zinc powder mixer Water sealing pump Frame filter press Poor solution pool
Zinc powder displacement process has 3 steps including pregnant solution purification, deoxidation and zinc powder filtering replacement.
Principle: Gold pregnant solution often contains suspended solids which should be removed before replacement. Pregnant solution purification is the process to remove suspended solid.
Tube type filter
Frame purification tank
Frame press filter
Work Principle: Dissolved oxygen in pregnant solution hinders displacement of zinc and gold.
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.
