Copper: smelting, producing and classification-Metalpedia
Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

Blister Tap-Hole Refractory Insert Life. Unlike slag or copper matte, blister cannot be tapped through a water-cooled copper element. Contact of molten blister with a water-cooled copper element typically results in a rapid dissolution of the copper element, which eventually may cause a steam explosion or furnace leak with serious …
Closed-Loop Recycling of Copper from Waste Printed Circuit
In the present study, a model of closed-loop recycling of copper from PCBs is demonstrated, which involves the sequential application of bioleaching and electrowinning to selectively extract copper. This approach is proposed as part of the solution to resolve the challenging ever-increasing accumulation of electronic waste, e-waste, in the …
