Patent ID: 8734563

Claim:
A method of production of Zinc dust, which comprises pre-heating a melting furnace to a temperature of between 400° C. to 700° C.; melting Zinc products in the melting furnace to form molten Zinc products; reducing the temperature of the molten Zinc products to about 550° C.; transferring at least a part of the molten Zinc products to a vaporizing furnace using molten material transport means being in flow communication with the vaporizing furnace and a dip tube with a top end of the dip tube being in flow communication with the molten material transport means and a bottom end of the dip tube extending into a the crucible in the vaporizing furnace; maintaining the molten Zinc products in the vaporizing furnace at a pre-defined level above the bottom end of the dip tube; vaporizing the molten Zinc products in the vaporizing furnace into Zinc vapour; transferring Zinc vapour from the vaporizing furnace to a condenser; and condensing the Zinc vapour to form Zinc dust.
