It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals such as aluminum. The aluminum in cans has already been smelted - I am just melting cans to extract the already "pure" aluminum. Aluminum is almost always alloyed, which markedly improves its mechanical properties. For example, beverage cans are typically alloys that contain by weight 1% magnesium, 1% manganese, .4% iron, .2% silicon, and .15% copper. When melting beverage cans, a lot of waste is produced (called dross) which needs to be removed from the top of the molten aluminum before pouring. The dross produced from melting beverage cans is oxidized waste material that includes the ink used to print the labels and the inner plastic liner. <br />John Wellshttps://www.blogger.com/profile/12783305402239706779noreply@blogger.comtag:blogger.com,1999:blog-6120586935905234915.post-86961857440494792072021-03-16T20:26:45.864-05:002021-03-16T20:26:45.864-05:00Smelting?
