Waste Metal Recycling & Processing Plant
Metals can be classified as ferrous, or non-ferrous. Ferrous metals
are combinations of iron with carbon. Some common ferrous metals
include carbon steel, alloy steel, wrought iron, and cast iron.
On the other hand, non-ferrous metals include aluminum, copper,
lead, zinc, and tin. Precious metals are non-ferrous. The most
common precious metals include gold, platinum, silver, iridium, and
palladium.
1. Collection
Waste center will make simple collection for metal waste
2. Sorting
Sorting involves separating metals from the mixed scrap metal
stream or the mixed multi-material waste stream. In automated
recycling operations, magnets and sensors are used to aid in
material separation.
3. Processing
To allow further processing, metals are shredded. Shredding is done
to promote the melting process as small shredded metals have a
large surface to volume ratio.
4. Melting
Scrap metal is melted in a large furnace. Each metal is taken to a
specific furnace designed to melt that particular metal. A
considerable amount of energy is used in this step.
5. Purification
Purification is done to ensure the final product is of high quality
and free of contaminants.
6. Solidifying
After purification, melted metals are carried by the conveyor belt
to cool and solidify the metals. In this stage, scrap metals are
formed into specific shapes such as bars that can be easily used
for the production of various metal products.
7. Transportation of the Metal Bars
Once the metals are cooled and solidified, they are ready to use.
They are then transported to various factories where they are used
as raw material for the production of brand new products.
When the products made of these metal bars come to the end of their
useful life, the metal recycling process cycles again.
