Copper extraction - Wikipedia

The slag layer is periodically allowed to flow through a hole in the wall of the furnace above the height of the matte layer. The matte is removed by draining it through a hole into ladles for it to be carried by crane to the converters. This draining process is known as tapping the furnace.

What is a Copper Slag? (with pictures) - wisegeek

Aug 23, 2019 · Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.

· Slag is formed from the gangue materials of the burden and the ashes of the coke and other auxiliary reductants. During the blast furnace process, slag is formed in two stages: first "primary slag," and "primary slag " develops then to a "final slag." Four main components (SiO 2, CaO, MgO, and Al 2 O 3) make up about 96% of the slag.

Innovations: Introduction to Copper: Mining & Extraction

A dc electric current, passed through the cells, dissolves the anodes and deposits the copper on cathodes. The final product of the refining process is electrolytic tough pitch (ETP) copper normally containing between 99.94 and 99.96% Cu. Cathodes are re-melted under controlled conditions and cast into forms suitable for further processing.
