The recycling rates of metals in the UK are generally higher compared to many other countries due to well-established recycling infrastructure and government initiatives. In particular, the recycling of metals like aluminum and steel tends to be more successful in the UK. However, there are still variations among countries, and some may have more advanced recycling processes for specific metals.
Metals can be efficiently separated in a recycling process using methods such as magnetic separation, eddy current separation, and density-based separation techniques. These methods rely on the physical properties of the metals, such as their magnetic properties, conductivity, and density, to effectively separate them from other materials in the recycling stream.
Water and oxygen can be used to compare the reactivity of metals. More reactive metals will react with water to form metal hydroxides and hydrogen gas, and with oxygen to form metal oxides. Less reactive metals may not react with water or oxygen at all.
Electrum, a natural alloy of gold and silver, has lower conductivity compared to most pure metals. While it conducts electricity, it is not as efficient as metals like copper or silver.
Tungsten has a very high melting point compared to other metals. It requires extreme heat, around 3,422 degrees Celsius, to melt tungsten, making it one of the metals with the highest melting points.
Three sources of silver include silver mines, recycling of silver from electronic waste and other products, and extraction as a byproduct of mining for other metals like copper, lead, and zinc.
The Magnets are often used for the separation of metals in many of todays most common recycling applications such as automobile recycling, recycling of electrical goods, skip waste, domestic waste and in fact, wherever there is a need to separate ferrous and non-ferrous metals from other materials.

Two drawbacks of recycling copper are that it causes secondary pollution and it is harder to purify in the event of other metals getting into it.
Metals can also be sourced from recycling scrap metal, by extraction from seawater or from deep-sea deposits, and by recovering metals from electronic waste. Additionally, metals can be sourced from meteorites that have fallen to Earth.

The metals in the living things usually are combined with other elements in chemical compounds.
Recycling of mobile phones is just like recycling any other recyclable wastes. It is important because the mobile phone contains a lot of metals, plastics and other materials (flame retardants, ceramics) which the planet desperately needs us to recycle.

Computer monitors, particularly older ones, contain lead and other heavy metals. Many are toxic and so recycling them is better than dumping them.
