· Angola's underground is also abundant with other minerals. From 1950s through 1975, iron ores were explored in provinces such as Malange, Bié, Huambo, and Huíla, and average output reached million tons per year between 1970 and 1974. The most explored minerals were exported to Japan, Germany, and the United Kingdom, earning Angola 50 million a year. In addition to iron .
