It is carried out in the zinc wire replacement box by replacing the gold with
the zinc wire from the gold-containing liquid. The technical operation is as
follows:
1. Zinc wire added zinc wire should be loose, evenly spread to the box on the
screen, can not stay through the hole. And each class must add the right amount
of zinc wire to supplement consumption. In order to keep the zinc wire loose,
usually should always mention the handle up and down jitter, to promote the
surface attached to the zinc wire gold sink to the bottom of the box, so that
zinc wire exposed fresh surface, and timely discharge of hydrogen, to facilitate
the replacement process can be carried out smoothly.
2. Production inspection production should always observe whether the
abnormal, if the zinc surface appears white precipitate, should be appropriate
to add cyanide; found zinc wire surface was yellow and red, indicating high
copper content, should take timely measures to discharge copper interference ;
If the zinc wire surface is covered with mud, indicating that too much suspended
solids in your liquid, should strengthen the purification operations. In
addition, you can also add a new zinc wire surface to determine whether the
reaction rate is normal.
3. Extraction of gold mud before the extraction of gold mud should first stop
the supply of liquid, and then extract the gold mud. It is best to stop the
supply of liquid to the box for the poor liquid, so that the top of the box
without the replacement of the liquid, when the box filled with liquid, to be
clarified for a while and then extract the gold mud.
