Abstract
A method of production of Zinc dust which includes melting Zinc products in a melting furnace on a semi-continuous basis, transferring at least a part of the molten Zinc products to a vaporizing furnace, vaporizing the molten Zinc in the vaporizing furnace into Zinc vapour on a substantially continuous basis, transferring Zinc vapour from the vaporizing furnace to a condenser, and condensing the Zinc vapour to form Zinc dust.
Claims24
A Zinc dust production plant, comprising:
- a vertical crucible melting furnace into which Zinc products are receivable;
- a vertical crucible vaporizing furnace into which molten Zinc products from the vertical crucible melting furnace are receivable via a dip tube with a top end of the dip tube being in flow communication with molten material transport means and a bottom end of the dip tube opening into a lower portion of a vaporizing crucible;
- and
- a condenser in fluid flow communication with the vaporizing furnace for receiving Zinc vapour into the condenser, the condenser operable to condense the vaporized Zinc into Zinc dust.
