What Are Obstacles To Mining Iron And Magnesium Silicate

Apr 10, 2021

The simplest silicate structure, that of the mineral , is composed of isolated tetrahedra bonded to iron and/or magnesium ions. In olivine, the −4 charge of each silica tetrahedron is balanced by two (i.e., +2) iron or magnesium cations. Olivine can be either Mg 2 SiO 4 or Fe 2 SiO 4, or some combination of the two (Mg,Fe) 2 SiO 4
