First Quantum Minerals brings largest acid plant on-line in Zambia

When you mine copper ore from a very productive source, you also need an efficient way to smelt all that ore and clean the off-gases from that smelting process. The Kansanshi mine in Zambia, the largest copper mine in Africa, is just such a source. But the nearest smelters were 180 kilometers away, in the county’s Copperbelt region. That is, until a new copper smelter, complete with the world’s largest single-train metallurgical gas cleaning and sulfuric acid facility, was built on site.
