Mining Corporation Autlan is planning to invest US$300 million in Mexico for an operational improvement of its iron alloy plants and an increase of its manganese portfolio, said Oscar Maldonado, General Director of the Corporation. The head executive highlighted that  the plan is to first increase the number of manganese nodes in reserve, despite being the Firm  with the largest portfolio of this mineral in North America and the second most important in the world. He also said that these funds will be used for operational enhancement of its iron alloy plants, a material on demand at the steel complexes in North America, primarily those located in the US.
