These inventions needed copper parts and electrical wires. Electrical wire mills switched from making iron wire to making a new kind of copper wire in 1877. This copper wire was strong enough to be strung overhead for new telephones and the older telegraph system. The copper industry boomed throughout the United States.

While gold, silver, and copper are sometimes found in their elemental state and not associated with other metals, that is infrequent except for placer gold. Zinc and lead are always chemically tied up with other elements. It is the chore of the mill manager to decide what methods or techniques will be used to obtain the valuable commodity.

The slag, with iron to silica ratio of 1.0 results in 25.8% of copper, which was returned to the slag blow step of converting. Process air for the copper blow has an oxygen enrichment of 22.2% and the oxygen in off-gas, treated together with the gas from slag blow, was set to be 2.5% ( Outotec 2021; Schlesinger et al., 2011). 2.3.

Melting points of Copper Alloys (including bronzes, pure copper, and brass) are lower than iron, at ranges around 1,675-1,981°F / 913-1,082°C. Aluminum Alloys have a lower temperature range than copper alloys. Pure aluminum melts at about 1,218 °F / 659 °C, but alloying with other elements can raise this.
