I am collecting information about copper refineries in the world and the different costs they have, as well as the efficiency of their processes and regulation of greenhouse gas emissions.
Once, I had a contact with the International Copper Study Group which is an organization of 24 world leading countries including India. They have a very refined and updated database on their website which you can access with the help of your library may be. (http://www.icsg.org/index.php/who-we-are/members-&-observers)
Further, many other organizations are also formed to deal with the Copper metal and its effects and cost. But I would suggest you to contact ICSG.
