  • The lowmelt metals (i.e. zinc, lithium, and cadmium) separate during the melting operation and are collected as a metaloxide. Lithium battery recycling process. The contents of the batteries are exposed using a shredder or a highspeed hammer depending on battery size. The contents are then submerged in caustic (basic not acidic) water.

  • 2 Zinc can be produced by a process called froth flotation, which is also used for reduction of copper and lead ores. This process involves grinding the zinc ore to a fine powder, mixing it with water, pine oil, and flotation chemicals, and then agitating the mixture to "float" the zinc to the surface.

  • Steel and iron are the most recycled materials in the world due in part to the opportunity to recover large structures as well as the ease of reprocessing. The use of magnets in the sorting process enables recyclers to easily separate them from the mixed waste stream. Every year, around 400 million tons of metal are recycled worldwide.
