Abstract

Experiments were carried out with two different sizes of (−30 + 6 and −6 + 1 mm) sub grade iron ore sample from Deposit No. 10 and 11A, Bacheli Complex, Bailadila, India to study the stratification behaviour at optimised parameters in a under bed air pulsed jig at 1, 2, 5, 10, 15 and 20 minutes residence time. This paper deals with the rate at which stratification takes place and determines the optimum stratification time (residence time) for above two size fractions. Average apparent density along with Jig Stratification Index (JSI) of both the size fractions was calculated. It was observed that the stratification rate is high for fines (−6 + 1 mm) and stratification index was higher for lump (−30 + 6 mm) when compared with the other size fraction. The maximum JSI observed was 0.35 for lump (−30 + 6 mm) and 0.30 for fines (−6 + 1 mm).
