The Rhodesia iron company was founded in 1902 and began the iron mines of Kafue and Bwana Mkubwa develop. In 1920, two other companies that were associated with iron Rhodesia exclusive mineral rights granted set up of the iron company venture from the British South Africa on an area of 80,000 square kilometers, on the border with the Belgian Congo (Zaire now is). Another mining company, Tanganyika concessions already 1899 established mining rights in Zambia was given by British South Africa, and Zaire by the King of the Belgians. Founded in 1906 the company in cooperation with the Belgian State, you the Union Minière Haut Katanga which much later was in the Katanga secession for the independence of the Congo.

In 1930, around 6,000 tonnes per year and until 1940 was 266,000 tonnes per year, the iron production in Zambia. Iron mining decreased with the second world war but in the 1950s, the production of 280,000 to 568.000 tons per year increased. New mines were opened as Chimacum in 1951 in 1952 Luba, Bancroft and Kansanshi in 1953 and Nchanga in 1955. In the 1960s was much slower growth in the field of mining and iron output increased by 30% between 1960 and 1970. Here the production growth reflects the worldwide demand for copper, then very quickly increases tend to stabilize the. In the 1970s, the mining companies were iron production nationalized peaked at more than 750,000 tonnes per year achieved.
Such a level should be achieved never again in the 1970s a decade that the crisis of iron marked specialization
