Metals are necessary, versatile, and may be employed in a variety of applications. Metal recycling has the advantage of being able to be recycled multiple times without losing its qualities. Aluminium and steel are two of the most commonly recycled metals. Silver, copper, brass, and gold, for example, are so expensive that they are rarely thrown away to be recovered for recycling. As a result, they don't cause a waste disposal dilemma or issue.
Chemical precipitation, flotation, adsorption, ion exchange, and electrochemical deposition are some of the traditional methods for removing heavy metals from wastewater. The most common method for removing heavy metals from inorganic wastewater is chemical precipitation.
