Metal separation of Incineration slag

Metal separation of Incineration slag

With the continuous acceleration of urbanization, the issue of garbage disposal is also receiving increasing attention. The traditional landfill method has been unable to meet the needs of urban waste treatment, and Incineration has become an increasingly popular treatment method. However, the slag produced by Incineration contains a large number of metals. How to effectively separate and recycle these metals has become an urgent problem to be solved. This paper will introduce a method of metal separation from Incineration slag.

I. Principle of metal separation of Incineration slag

Metals in Incineration slag mainly include iron, copper, aluminum, etc. These metals can be separated through various methods such as magnetic separation, airflow separation, and gravity separation. Among them, magnetic separation is a commonly used sorting method. Due to the fact that iron is a magnetic material, it can be separated by magnetic separation. For non magnetic materials, they can be separated by the action of airflow and gravity.

II. Operation steps for metal separation of Incineration slag

1. Slag crushing: Crush the Incineration slag to make it become smaller particles, which is convenient for subsequent sorting and treatment.

2. Magnetic separation: The slag particles are subjected to magnetic separation treatment to separate the iron from them.

3. Air flow separation: The slag particles processed by magnetic separation are separated by air flow separation to separate non magnetic metals such as copper and aluminum.

4. Gravity separation: The slag particles after airflow separation are subjected to gravity separation to separate the heavy metals from them.

5. Recycling treatment: The separated metal can be recycled and transformed into reusable materials through melting, processing, and other methods.

III. Advantages of metal separation of Incineration slag

1. Improve resource utilization rate: By sorting and recycling the metals in Incineration slag, it can improve resource utilization rate and reduce resource waste.

2. Reduce environmental pollution: Incineration slag contains a lot of metals, which will pollute the environment if not recycled. Through metal sorting and recycling, environmental pollution can be reduced.

3. Energy conservation: Through metal recycling treatment, energy can be saved and dependence on natural resources can be reduced.

4、 Application prospect of metal separation of Incineration slag

With the continuous acceleration of urbanization, garbage disposal has become an urgent problem to be solved. Incineration, as an efficient and environmentally friendly waste treatment method, will receive more and more attention. As an effective way of metal recovery and treatment, the metal separation of Incineration slag will also be widely used.

In a word, metal separation from Incineration slag is a very important technology, which can effectively solve the problem of metal recovery from Incineration slag. Through metal sorting and recycling, resource utilization can be improved, environmental pollution can be reduced, and energy can be saved. It is believed that in the future, the metal separation of Incineration slag will be more widely used.
