The iron formed in a blast furnace is called pig iron, which contains impurities that make the metal brittle. What are these impurities, and how did they come about? Why is it important to perform the ammonia tests with no other sets of cations in the tray?
Because copper may be alloyed with metals that may be dangerous, or not meet customer specifications, the scrap needs to be analyzed, identified, and sorted when it arrives at the metal recycling facility and then quality checked before it is shipped to a customer. Then it should ...
