How to properly recycle and dispose the scrap metals

There are many ways to recycle and dispose of scrap metals. Here are some common ways to deal with them:

Classification collection: First of all, scrap metals should be collected and classified according to their materials. Different types of scrap metals should be collected and stored separately, such as copper, aluminum, steel, etc. This will facilitate subsequent processing and utilization.

Physical crushing: Use a scrap steel crusher for crushing, then use a sorting machine to sort out metal particles, remove impurities, and finally conveyor to sort and pile them.

Remelting: All kinds of metal waste can be recycled by melting. Remelting is to put scrap metal into a high-temperature furnace and extract the metal elements from it by melting. The extracted metal can be used to make new products.

Repair and reuse: Some scrap metals can be recycled by repairing and reuse. This method is to repair or process scrap metal materials to make them into new products. For example, scrapped auto parts can be repaired and reused by welding, grinding, etc.

Electrochemical stripping method: For some scrap metals with precious metals on the surface, electrochemical stripping method can be used for treatment. This method separates precious metal ions from the surface of scrap metals through electrochemical reactions, and then recycles them.

Mechanical treatment: For some large scrap metal products, mechanical treatment can be used for recycling. Mechanical treatment is to cut, crush, grind and other methods of scrap metal to make it into smaller particles or powders, and then smelt or extract them.

Chemical treatment: For some special scrap metals, chemical treatment can be used for recycling. Chemical treatment is to react scrap metals with chemical reagents to extract the metal elements in them, and then separate and purify them.

In the process of handling scrap metals, attention should also be paid to environmental protection. Wastewater, waste gas, waste residue, etc. generated during the scrap metal treatment process need to be properly handled to reduce pollution to the environment. At the same time, we also need to pay attention to the rational use of scrap metal to avoid wasting resources.
