1.	Smelting is done to eradicate unwanted materials like ___________ to the fullest extent possible.(a) copper(b) copper and gangue minerals(c) sulfur(d) sulfur and gangue mineralsI have been asked this question by my college director while I was bunking the class.Asked question is from Manufacturing Processes of Copper and its Alloys in chapter Copper and its Alloys of Aerospace Materials & Processes
Answer» Correct option is (d) sulfur and gangue minerals To EXPLAIN I would SAY: Smelting is done to ERADICATE unwanted materials like sulfur and gangue minerals to the fullest extent possible. The output of the smelting phase is CALLED COPPER matte. It is a combination of sulfur, copper and iron.
