One of the most produced and used material in the world is metal. The good thing about metal is that it could be recycled over and over. Because of the advancements in recycling different metals, it is now considered a profitable business opportunity that also contributes to the preservation of the environment.
According to recent studies, an average of around 400 million tons of metal per year is recycled worldwide. This comprises almost 40 per cent of steel production worldwide.
Metal salvaging is not only for companies and businesses but for households as well. It is essential to learn about metal recycling because much like other waste there are different kinds of metals.
Metals are segregated through the use of magnets. Most ferrous metals react to a magnet because of the presence of iron and carbon. Carbon and alloy steel, wrought and cast iron are some of the most common ferrous metals. Ferrous metals contain iron, and by contrast, non-ferrous metals do not contain iron. Non-ferrous metals range from the common aluminium, copper, lead, tin and zinc to the most precious non-metals like gold, silver and platinum as well as iridium and palladium.
Metal Recycling Process
The recycling of metal starts with the collection. The sorting of metals employs the use of magnets and sensors as well as scrappers. They not only separate dirt from the metal, but they can also determine the type of metal based on its colour. There are modern sorting processes currently being developed to hasten the process for non-ferrous metals which could remove any physical human contact reducing health risks.
Before the metal is melted, it is shredded into small pieces so it will use less energy. To ensure the quality of the recycled metal, it also undergoes the purification process called electrolysis. Finally, the melted metals are brought to its solidified raw form before being transported to various facilities.
Compared to ore processing, recycled metal uses less energy to form new metals. This is a big leap to conserving the environment for future generations. It’s unfortunate that only approximately 30 per cent of waste metal is recycled according to reports. Bringing your scrap metals to a nearby metal recycling facility would be not only profitable but also good for the environment.
