3.1 Chrome magnetic separation process. The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite.
A pilot plant with a capacity of 100 lb/h was designed, constructed, and tested using stage grinding, classification, tabling, vanning, and flotation techniques to concentrate chromite from fine-grained ores.
You need to complete "The Pit of Judgement" tomb, which then unlocks the "Geologist" skill. After doing that, go look for ore veins (e.g. in caves) and you'll find some now also contain Chromite Ore.
