What pattern can be seen in the location of plants for the production of ferrous metals and ore-processing plants?

The stages of mining and processing of ores are more represented in developing countries, this is due to the tectonic features of these territories, it is in developing countries that the reserves of non-ferrous metal ores are concentrated. For example, the share of aluminum ores located in developing countries is 1/2, and the share of tin, and the upper levels of metallurgical production (obtaining pure metal) are in developed countries, since this is a cleaner production, but also more energy intensive.
