In the present study, it has been attempted an innovated application, i.e., electromagnetic interference shielding material, to reutilize copper smelter slag, aiming at an alternative high value added product.
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.

"(Facility) Huelva Copper Smelter" is a plant deposit site in Spain Territory, Spain. It is a deposit, considered to be of world-class significance. 1 Copper and sulfur, sulfuric acid deposits are documented at "(Facility) Huelva Copper Smelter."
The process includes three operations similar to copper and nickel slag production: (1) roasting, (2) smelting, and (3) converting. Lead and zinc are often related as coproducts in both source and metallurgical treatments, and the various combinations of slags, which include lead, lead-zinc, and zinc, are similarly produced.
