17.03.2016The slags contain copper with the content ranging between 0.8 to 5% copper. The slags cannot be discarded due to the high content of copper and hence they are sent to a milling and flotation plant (Slag Mill Plant) for liberation and recovery of copper. This work focuses on optimizing the recovery of copper minerals in copper smelter slags by

11.09.2009In any copper smelter large quantities of copper slag are discarded as waste material causing space and environmental problems. This discarded slag contains important amounts of metallic values such as copper and iron. The recovery of copper values from an Indian smelter slag that contains 1.53% Cu, 39.8% Fe and 34.65% SiO

It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agentto decompose the ore, driving off other elements as gases or slagand leaving the metal base behind.

Copper slag was characterized and processed. The pyro-metallurgical processing prospects to generate utilizable materials were arrived at through rigorous thermodynamic analysis. Carbothermal reduction at elevated temperature (near 1440C) helped recover a majority of the metal values (e.g., Fe, Cu and Mo) into the iron-rich alloy product

31.12.2019The copper content in the slag increased as the oxygen partial pressure increases, and thus with pO2 = 10 −5 and 10 −6, the slag was not capable of holding the dissolved copper during quenching. As the segregated copper in these high pO2 experiments was part of the slag at the equilibration temperature, they were included in slag analyses. Fig. 3

"Copper slag" will be the slag skimmed off molten copper in a furnace. It is generally formed from limestone or phosphate rock added to the furnace, which melts and reacts with impurities in the metal before floating to the top where it is skimmed off and discarded. The slag usually contains a small number of metal droplets that didn't separate.

The European Copper Institute defines copper slags as "Substance produced at high temperature in a liquid state, by melting mixtures of metal oxides and non-ferrous metals (from primary sources such as copper ores, matte or anodes) or by oxidizing metals (from copper rich materials such as metals, alloys or metal oxides)".

At the Inspira- tion plant, slag is poured off and transferred in ladles via the EOT crane and charged into the electric smelting furnace for recovery of the copper. As with the Peirce-Smith converter, the slag blow is fol- lowed by the blister copper blow. The copper sulfide bath is blown until all or nearly all of the sulfur is burned off, mainly oxidized as S02. Upon completion of the
