Modeling the Liberation of Quartz in Low-Grade Iron Ores
Anshan-type iron deposits are associated with Neoarchean volcanic sedimentary strata, which are mainly low-grade ores (20–40% total Fe), with magnetite as the main ore mineral. From Fig. 3, it can be observed that the ore texture of the three types of iron ores from different Anshan-type iron deposits has obvious differences.
