Re... mike ... Why vs mgx
WHYs MgO is 39.8% and there are 3 serpentine subgroups WHY has lizardite NOT chrysotile Asbestos)
And it also doesn't contain carbon dioxide which is released by other mgo sources
Serpentine is a subgroup of the Kaolinite-Serpentine Group, usually trioctahedral, with divalent cations dominating in octahedrally coordinated sites. The most common species are all Mg-dominant: lizardite, chrysotile (both low-temperature phases) and antigorite (high-temperature phase). They are chemically similar to talc (Mg-poorer, with Mg:Si = 3:4). Serpentine minerals are the major components of the rock serpentinite. One of six "minerals" proposed to be essential for life emergence (Russell & Ponce, 2020).
17.2.1.2 Raw Material
The chemical composition of the raw material feed? to the plant is shown in Table 2. The particle size distribution is assumed to be P80: 235-300um.
