The process of micronization is one of the steps in the development of mining, seen as one of the main parts following ore dressing.
In this sense, this step holds a great responsibility. Because micronization is in charge of the finest ore fragmentation.
In this stage, certain procedures contribute to leaving the ore fine. Through impact, compression, abrasion, and friction, the ores get a smoother texture.
It is worthy to point out that there are two standards of grinding, the fine, and the ultrafine; however, each one has its purpose.
For you to know the difference between them, to understand the importance of micronization, also known as grinding, keep on reading this article.
Micronization: What is ore processing?
Ore treatment has the purpose of changing the granulometry.
Granulometry has the function of determining the size of the product and its particles without changing the chemical or physical identity of the minerals.
Thus, this process seeks to turn the material that goes through grinding suitable for any other industrial activity in which the mineral has an application.
Micronization is one of the most sought-for milling standard; because it results in the milling of ultra-fine ores.
Micronization: what are the advantages of this procedure?
Like many steps in a process, some tend to be more beneficial than others, but it is important to always consider what you expect as a final result.
In other words, if you are looking for a certain result, the ideal grinding for you may be fine, for others, ultra-fine works better.
A highlight is that ore grinding has great benefits, starting with:
However, it is noteworthy that, in short, micronization is a generalized term to describe the reduction of particle sizes through grinding.
Thus, to differentiate fine grinding from ultra-fine grinding, you need to know that when the particle size is less than 100 µm, it is fine and ultra-fine when lesser than 10 µm.
Micronization: what benefits does this process step offer?
One of the benefits of passing the ore through this stage of milling/micronization is that it improves the quality of the product. In this sense, since it automatically has a quality gain, then value is aggregated at the time of exportation.
In addition, micronization converts the raw material into the final product. We must not forget that the micronization process uses a cylindrical rod, ball, hammer, or pebble mills.
They are responsible for doing the most refined grinding, fine or ultrafine grinding results from this process.
Micronization: it all starts with mining
Before the micronization process starts, you have to go through the first stage, the mining stage.
This is where it all begins, with the search for raw materials, and from there, things begin to take shape and direction.
This is because micronizing, also called grinding, is one of the mining processes.
Micronization: raw material stages from beginning to end
Before reaching the micronization, the ores go through some stages, and after micronization, the material still goes through other processes, see what they are:
1) Crushing: it is a set of methods used to fragment the solids. The idea is to obtain products in granulometries finer than those of regular occurrence.
2) Grinding: also known as the micronization process.
3) Classification: the process of separating the solid particles.
4) Screening: separates the material into two or more classes, having their lower or upper limits.
Each of these steps is important to reach the final goal. The process is similar to a gear; they complement each other.
As you can see, in ore treatment there are several steps to achieve the final result from the raw material.
Conclusion
Ore processing is a bit extensive, but in the end, the quality and the final work are worth it.
In this article, you learned about what micronization is and how important it is in the process. After all, it is through micronization the ore gets more quality and a purpose.
You also learned that after the ore has passed through the grinding mill, it also requires further steps.
These are comminution (crushing), grinding, dry screening, screening, and agglomeration, among others mentioned in this article.
Each step contributes to the result of the final product being profitable and of high quality, thus contributing to better use of natural resources and increased financial transactions in the country.
