effect of crushing manganese ore on the environment

Impacts of manganese mining activity on the environment ...

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.

Use of manganese ore in chemical-looping combustion

2012-5-1  Operation in a 10 kW CLC unit for solid fuel using a manganese ore, with even lower Fe content, indicated an unexpected and significant effect on the rate of steam gasification of char (Linderholm et al., 2011). The purpose of the present work is to verify these results and quantify the effect of this manganese ore on steam gasification. 2.
