Using chalcocite as raw material without adding flux, silica would precipitate in the melt, which is not conducive to the smelting. Theoretical calculations and experimental results indicate that the DB copper smelting of chalcocite can be achieved with 0.6 ratio of iron to silica and 6.4 wt.% CaO at 1300 °C.

Manufacturing Process of Copper. Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.

The removal does, however, mean more energy intensity to regrind as well as increased complexity of flotation – driving higher capital and operating costs. Smelter energy intake relies on the input quality. Volumes, or throughput, and quality of the raw material drive both mining but also smelting energy requirements.
