With the development of industry, the production of power plant slag as a waste is also increasing day by day. In the slag, there are not many metal elements, so the sorting work of the slag is particularly important. This article will introduce the process flow of metal sorting for power plant slag, hoping to be helpful to readers.
1、 The significance of slag metal sorting
The main purpose of metal sorting in power plant slag is to recover the metal elements, reduce the amount of waste, and also reduce the degree of environmental pollution. In the slag, the metal elements mainly include iron, copper, aluminum, etc. These metal elements can be recycled and utilized to reduce resource waste.

II. Steps for sorting slag metal
1. Collection of slag
Firstly, it is necessary to collect the slag from the power plant and concentrate it in a designated site for treatment. During the collection process, attention should be paid to the classification of slag, and different types of slag should be collected separately to facilitate subsequent processing work.
2. Crushing of slag
Crush the collected slag to make it finer and facilitate subsequent metal separation work. During the crushing process, attention should be paid to ensuring the quality of the slag to avoid excessive dust or deformation of the slag.
3. Slag metal separation
After the slag is crushed, metal separation work needs to be carried out. The commonly used metal separation methods currently include magnetic separation, gravity separation, and flotation. Among them, magnetic separation is the most commonly used method, which can effectively separate metals such as iron, but the separation effect for other metals such as copper is not ideal. Therefore, in practical applications, it is necessary to choose according to different types of slag and metal elements.
4. Post treatment of slag
After metal separation, it is also necessary to carry out post-treatment work on the slag. Mainly including the drying, screening, packaging and other work of slag. During the post-treatment process, attention should be paid to ensuring the quality of the slag and avoiding secondary pollution and other issues.
3、 Precautions for sorting slag metal
1. Ensure the normal operation of the equipment
In the process of slag metal sorting, various equipment needs to be used for processing work. Therefore, it is necessary to ensure the normal operation of the equipment and avoid problems such as malfunctions.
2. Safety production
In the sorting work of slag metal, it is necessary to pay attention to safety production. Especially in the process of slag crushing and metal separation, it is necessary to ensure the safety of workers.
3. Classification of slag
In the process of collecting slag, it is necessary to classify different types of slag. This can avoid mixing different types of slag together and affecting subsequent treatment work.
4、 Conclusion
The metal sorting process of power plant slag is a very important task, which can effectively recover metal elements and reduce resource waste. In practical applications, it is necessary to choose according to different types of slag and metal elements, while also paying attention to issues such as safety production and slag classification. I hope this article is helpful to readers.
