Methods Of Nonferrous Metal Recycling



In a world that is increasingly demanding for sustainability, the recycling of non-ferrous metals has become a very important practice. Choosing to recycle not only means protecting the environment and reducing carbon footprint, but it is also a very meaningful business in an industry that relies on the use of non-renewable resources.

However, recycling non-ferrous alloys can be challenging because they are not always in pure form. They are often found in all sorts of liquid and solid mixtures from which they must be extracted and purified before further use. The three methods currently used to recycle non-ferrous metals are electrowinning, precipitation, and non-ferrous sensors.

Electrowinning:

Electrowinning, also known as electroextraction, is a relatively simple process, at least on the surface, to extract dissolved metals from their dissolved state using electricity. In this way, non-ferrous metals such as copper, tin, nickel, or silver are recovered and easily accessible for further reuse.

Precipitation:

The second method for processing non-ferrous metals is precipitation. It is also the most widely used method for reducing metals from aqueous solutions. Rainfall can also be used for wastewater treatment. This is a process in which metals are extracted from aqueous waste solutions. This process involves two methods for removing metal called coprecipitation and adsorption. 

Metal Sensor:

Finally, non-ferrous metal sensors are increasingly being used in the sorting and extraction of non-ferrous metals from scrap, most of which come from end-of-life vehicles or electronic scrap. For example, sensors are used to detect and extract certain non-ferrous metals from zebras.
