Although copper had been produced at Kansanshi and Bwana Mkubwa in 1908 and 1911, respectively, the first commercial mine in Zambia was established in Luanshya in 1928.
The owners of these mines were driven by the high demand and favourable prices of copper and the need to maximize their profits. Flotation technology for separating copper sulphide minerals from ores had been commercialized and this advance enabled large quantities of copper to be produced. The mine owners therefore invested in concentrators, smelters, and other metal extraction facilities.
By 1964, Zambia was a major player in the world copper industry, contributing over 12% of global output.
