The opportunity to process pure copper through additive manufacturing has been widely explored in recent years, both in academic research and for industrial uses. Compared to well-established fabrication routes, the inherent absence of severe design constraints in additive manufacturing enables the creation of sophisticated copper …
There are two specific types of ore deposits, copper oxide and copper sulphide, which are both processed differently on account of their different chemical structures. Yet, the most common source of copper ore is the sulphide ore mineral chalcopyrite, which accounts for around 50% of copper production in the world.
Additive Manufacturing (AM) has become a relatively common material forming technology these days, just like conventional processes (such as casting or forging). It makes it possible to produce components with complex geometries, often unachievable with conventional manufacturing processes. In order to be able to …
Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace …
