Modern copper smelting operations, however, are located around the world on all continents except Antarctica.

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised ...

Apr 10, 2016· 4. Even Copper dust has value Any copper dust, chips or in bits and pieces, will have a good value. Collect it carefully. It sells by the weight and you’ll make more money if you can melt it and get copper nuggets instead of an amorphous mass of copper scrap. 5. Stripe Copper Wire Always strip your wire before trying to sell it. Remember!

Jul 15, 2007· Early on I tried to melt down some copper wire into a buss bar to drop silver with. Much to my surprise I went thru an entire bottle of Oxy/Act torch gas and never suceeded in making the 50 gram copper ingot. If nickel is anything like melting copper, I don't want anything to do with it. It's just not cost effective on my scale of things.

Jul 21, 2016· Copper has a relatively low melting point, around 1075 degrees C. You can melt small amounts with a blowtorch. To melt enough for casting you’ll need a furnace of some kind. This need be little more than a couple of tin cans and some perlite insul...

Copper pipe has been used for plumbing for a long time because of its many great qualities, including durability, flexibility, resistance to bacteria and ease of installation. Copper pipe is also environmentally friendly since it can be recycled. This guide will show you how to solder copper pipes to ensure there are no leaks in or around your ...
