Mineral Magnetism | SpringerLink
The magnetic rate of pure magnetite is 42.8%. The low magnetic rate of iron ore indicates its high degree of oxidation and weak magnetism. In industry, iron ore with magnetic rate ≥36% is classified as magnetite. Iron ore with a magnetic rate of 28–36% is classified as semi pseudo hematite.

Stibnite is a primary Sb 2 S 3 mineral and belongs to the orthorhombic system (a 0 = 11.20 Å, b 0 = 11.28 Å, and c 0 = 3.83 Å), which has been found in huge crystals and crystal clusters in many regions. 19 Note that the natural pure mineral usually exhibits unfavorable electrochemical properties. 20 Hence, it is necessary to improve the ...
A general ore formation model for metasediment-hosted Sb …
The formation of native antimony in stibnite may have been due to ore-forming fluids with low oxygen fugacity, in which the element Sb was reduced to form native antimony. Low oxygen fugacity is unlikely to be associated with pure magmatic fluids, so we infer meteoric fluids with low oxygen fugacity participated in Sb ore formation ( Li et al ...
