Metal Recycling Process

Recycling is protecting the environment and the need for recycling has been stressed more than ever. Metal recycling involves certain steps for them to become viable raw materials again.

Collection

The first step is the collection of scrap metals. Millions of tons of scrap metal reach the industry. These can include tin cans, old appliances, and metallic industrial wastes. All the scrap is collected and sent for sorting in order to segregate the metal types.

Sorting

All the items that have been collected need to be sorted based on their chemical compositions, grades, and quality. While sorting, an important factor to be considered is separating recyclable items ones that are highly contaminated. For the recycled metal to be free of impurities, its base material also needs to be in good condition.

Processing

The next step is to place the scrap metal in a machine where it is compressed to be able to maximize space and reduce melting loss. This results in composite blocks (or bales) of metal.

Shredding

After processing, some of the metal is shredded cut into thin pieces. Steel items are cut into small blocks. Small sizes of blocks are easier for melting.

Melting

The raw materials are then placed on a furnace for melting. The molten liquid is purified using various methods. It is then cooled and sent to the mills to be converted into reusable products.
