Zinc Oxide Calcination Process

Description of Zinc Oxide Calcination Process:
Zinc oxide is mainly present in the form of white powder or red zinc ore. Zincite contains a small amount of impurities, such as manganese, so it shows yellow or red, when  Zinc oxide crystals are heated, there will be a small amount of oxygen atoms overflowing (at 800 ° C, overflowing oxygen atoms occupy 0.007% of the total), makes the material appear yellow,and restore white crystals when the temperature drops.

Introduction of Zinc Oxide Calcination Process:
The pulverized solid materials are calcined in oxygen, so that the useful components are converted to oxide, while removing volatile impurities such as arsenic, antimony, selenium, tellurium. Pyrite roasting preparation sulfur dioxide in the sulfuric acid industry, is typical oxidizing roasting. Oxidizing roasting is widely used in metallurgical industry, such as: copper sulfide ores, zinc sulfide ore, by oxidation roasting, get copper oxide, zinc oxide, at same time obtain sulfur dioxide.
