Chemistry - Recycling Metals

Mining and extracting metals from ores is an expensive process. Fortunately, metals can be used again.

The process of making them reusable is called recycling, and it is much cheaper than extracting metals from ores.

Recycling is done by melting down used metals, to produce a metals that is almost as good as new.

The Recycling Process

Before a metal can be recycled it needs to be collected and separated from any other metals. This ensures that the recycled metal is as pure as possible.

It is then melted down and poured into moulds. The metal cools into a solid block, ready to be made into a new product.

The most commonly recycled metals are steel and aluminium. Other metals are recycled too – these include:

Copper

Tin

Lead

Gold

Silver
