Introduction: Jig concentrator (jig separator, jig machine) is a equipment that drives pulses of water upwards through a thick bed of settled sediment to keep it loose and agitated.This achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. A typical jig consists of a water-filled tank known as …

4.1.1 Hematite (α-Fe 2 O 3) Iron is the 4th most abundant element in the Earth's crust and it exists mostly as an oxide because it is easily oxidized in air. Iron has 16 oxides and among these, hematite is the oldest known. Hematite is a red-brown solid that is extremely stable under ambient conditions. It is often the end-product of all other ...

Reduction roasting followed by a magnetic separation process was the traditional technique for iron separation. The conventional direct reduction of iron ores by coal occurs at around 1200 °C for 2–5 h, and the transformation of weak magnetic iron phases to Fe 3 O 4 /γ-Fe 2 O 3 via reduction magnetization roasting by biomass …

5 Application of gravity separator. Gravity separator is suitable for the treatment of ore or other materials with a large density difference between useful minerals and gangue. It is an effective method for treating ore, medium and fine (substantially bound to be larger than 25 mm, 25-2 mm, 2-0.1 mm) ore. In the treatment of fine slime (less ...

As hematite (Fe 2 O 3) was used as the magnetic mineral, Fe grade of the deposit obtained from chemical analyses were adopted to evaluate the separation performance. In case A, when slurry was fed from top to bottom, deposit from downstream side (A2, TFe = 68.09%) had a higher Fe grade than upstream deposit (A1, TFe = 60.29%).
