The mine is designed for a production capacity ranging between 2.2Mtpa and 2.6Mtpa of run of mine (ROM) manganese ore, with an operational lifespan of 26 years. It is expected to produce 2.4Mpta of directly shippable Mn ore by mid …
Regulatory Process. All industrial projects, including the underground Twin Metals Project, must navigate an extensive, complex regulatory process. The process will span several years and provide many opportunities for public input and comment along the way. All new mine projects must obtain a series of approvals to begin construction.

Iron (Fe) is a relatively abundant element in the universe. The sun and many types of stars contain iron in quantity. The Earth's core is thought to be composed mainly of iron. Iron is the fourth most abundant element in the Earth's crust. The most common iron ore is hematite (Fe2O3), from which iron metal...
The mining district of Molango in the Hidalgo State, Mexico, possesses one of the largest deposits of manganese (Mn) ore in the world. This research assessed the impacts of Mn mining activity on the environment, particularly the interactions among soil, plants, and arbuscular mycorrhiza (AM) at a location under the influence of an open Mn mine.
