Serpentine can be uncommonly Fe-rich, with XMg = Mg/ (Mg + Fe) < 0.8, and shows distinct compositional trends toward a cronstedtite endmember. Bulk rock and silicate fraction Fe (III)/∑Fe ratios are 0.6–0.92 and 0.58–0.8, respectively; our data show that 2/3 of the ferric Fe is accounted for by Fe (III)-serpentine.

Serpentinite - an overview | ScienceDirect Topics
Serpentinite (Fig. 7.12) is a metamorphic rock mostly composed of one or more of the serpentine group minerals that include antigorite, lizardite, and chrysotile.The serpentinite depicts fascinating shades of green color and usually layered and banded. The serpentinite is formed by the hydrous alteration and low-temperature metamorphic alteration of igneous ultramafic rocks.

gold processing - Mining and concentrating | Britannica
gold processing - gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …

However, with the increase of solid concentration, the yield stress of serpentine increased remarkably, especially in the range from 20 wt% to 30 wt%. When solid concentration reached to 30 wt%, the yield stress of serpentine was around 9 Pa, suggesting that there is a certain degree of aggregation in serpentine pulp.

Magnetite Concentration Methods
Serpentinite Serpentinite is a metamorphic rock that is mostly composed of serpentine group minerals. Serpentine group minerals antigorite, lizardite, and chrysotile are produced by the hydrous alteration of ultramafic rocks. These are igneous rocks that are composed of olivine and pyroxene ( peridotite, pyroxenite ).

According to the previously established knowledge, ball-milling serpentine can increase the disorder of the crystal structure, enhancing serpentine dissolution, and thereby facilitating the release of magnesium ions, silicon and hydroxyl groups (Drief and Nieto, 1999, Kim et al., 2008, Lei et al., 2019, Zhang et al., 1997).
