Zinc Oxide Production Process Direct and Indirect Methods
The zinc oxide production process can be done using a direct method or the French process, and an indirect method or the American process. The direct and indirect methods differ quite a bit, but both produce high-quality zinc oxide suitable for various needs. Here, we will discuss both processes in more detail.
Important Zinc Oxide Production Process to Understand
Zinc oxide is a beneficial mineral needed by many people. This is because this material is very valuable and has various benefits or unique advantages. This material is also often required as an ingredient in the manufacture of skincare, cosmetics, health products, and various other industries. Therefore, the demand and need for zinc oxide always exist.
The production of this mineral has several different methods or techniques, but they all produce high-quality products. Here, we will discuss two examples of these methods.
Direct Method
The first is the direct method, also known as the American process. In this method, the production of zinc oxide involves the initial production from the burning of zinc vapor. The zinc vapor itself is produced by the thermal decomposition of raw materials that contain zinc, whether zinc ore or zinc residue.
The burning of zinc vapor will then produce zinc oxide smoke. The next step in the zinc oxide production process is to collect the zinc oxide smoke and then cool it to obtain zinc oxide particles. These particles are then purified and further processed to achieve the desired characteristics and quality. This method is more energy and cost-efficient.
Indirect Method
Another way is the indirect method or the French process. The process starts with melting zinc metal and its evaporation. This process uses high temperatures up to 1100 degrees Celsius. The vapor that forms will later react with the oxygen in the air. The reaction results will then form zinc oxide particles. The producer will then collect these particles to process them further until they reach certain properties.
This indirect process can produce zinc oxide with a high level of purity. Therefore, it is not surprising that many producers choose to use this method, especially if they want to produce high-quality zinc oxide for various needs. For example, for skincare, cosmetics, and other important purposes.
The zinc oxide production process, whether by direct or indirect methods, is equally interesting and produces quality products. The steps that need to be taken are quite complicated, but are certainly worth the results that will be obtained. The produced zinc oxide can certainly be used for various purposes.
