Apr 03, 2014 · Jigging – Jigging is a gravity concentration technique where the iron ore is separated into light density fraction, medium density fraction and heavy density fraction. Size fraction of the iron ore used for jigging is mm to 30mm. Spirals – Spiral concentrators are flowing film separation devices.
Aug 25, 2018 · In this paper, a sample from Tangezagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main ironbearing minerals with insignificant amounts of FeO. The results indied that spiral separation yields higher separation efficiency than others. The combination of spiral and multi gravity methods .
Development of the gravity concentration flowsheet is discussed and the paper finishes with the description of two plants, one treating iron ore and the other cassiterite, as an indiion of the diversity of gravity concentration flowsheets.
