Abstract

The invention discloses a method for distilling zinc powder, which comprises the steps of: A. adding electrolytic zinc ingots into the distillation furnace through the zinc addition port of the distillation furnace to melt the zinc ingots; B. controlling the temperature of the distillation furnace at 907-1000 ℃, the molten metal zinc is vaporized and distilled in the distillation furnace; C, the vaporized metal zinc vapor enters the condenser through the air duct to cool down, and zinc powder is obtained. The invention has short technological process, simple production operation and low manufacturing cost; there is no waste water and waste gas in the production process, which meets the requirements of environmental protection; and the granularity of the product is fine, which meets the requirements of purification production.

Description

technical field [0001] The invention relates to the field of nonferrous metallurgy industry, in particular to a method for distilling zinc powder. Background technique [0002] Electrolytic zinc production requires a large amount of zinc powder for purification and comprehensive recovery of valuable metals. The zinc powder is required to be distilled zinc powder. Compared with electric furnace zinc powder and blown zinc powder, distilled zinc powder has the following characteristics: high purity (the purity is 99.998-99.9998%), and the particle size of zinc powder is fine and controllable (the particle size of the product can be controlled to be mainly distributed below 10 microns) , is a highly active reduced zinc powder, no oxide film on the surface of the zinc powder, and the effective zinc is more than 98.5%. This distilled zinc powder is widely used in chemical industry, zinc-rich paint, hydrometallurgy. [0003] Production practice shows that the use of high-purity ...
