Metals are versatile, essential and can be used in different ways. Metals are used for industrial purposes like the manufacture of railways, ships, airplanes, cars and trucks. They are also used to manufacture items for domestic purposes such as packaging, crockery and cutlery.
Basics of Metal Recycling
The appealing aspect of metal recycling is that it can occur over and over again without altering the metal’s properties. Commonly recycled metals include steel and aluminum. Other metals such as gold, brass, copper and silver, for example, are so valuable that they are rarely disposed of and collected for recycling. This is why they are not associated with a waste disposal problem or crisis.
The process of recycling metal is comparable to the usual recycling process. It begins with the metals being sorted according to their properties. However, it is important to have the basic knowledge or understanding of the metals in order for the process to be effective. This helps to recycle them efficiently and maintain a green environment. The recycling process of metal consists of a number of steps.
Collection is the first and most essential step during metal recycling. It involves collecting the materials that consist of metals. This is a process that should ideally be organized in a way that ensures there are containers that are specifically designed for collecting the metals at 27 Recycling.
Various scrap yards have been established and people are encouraged to gather different metals and take them to the yards where they are paid for their collections. Different metals are attached to different costs. Scrap metal yards often serve as collection centers for metals. Click here for 27 Recycling.
After the metals are collected, sorting the metals is the next important step. This consists of separating the materials that can be recycled from what is not recyclable. It is important to note that the quality of recycled metal is essential. High quality recycled items or products can be created when the original materials also exhibit good quality during the recycling process. A quality check is usually carried out in the sorting process.
The next step after sorting is to squeeze or compact the metal. This ensures that the metals do not occupy an excessive space in the conveyor belt.
After breaking and crushing the metal, the process of shredding begins. Metals are broken down into small sheets or pieces for further processing. Small pieces can be melted with less energy than large pieces of metal.
Scrap metal is melted in a large furnace. Furnaces are heated appropriately to melt a particular metal.
After completing the melting process, the purification process is next. Different methods can be used to purify metals, including electrolysis.
Once the metal has been purified, molten metal is carried way by conveyor belts to cooling chambers for cooling and solidification. During this stage the scrap metal becomes a solid metal for reuse.
Metals are transported to different factories where they can be used as raw materials to produce new products. When products of the metal bars reach the end of their usefulness, they can go through the recycling process again.
