Efficacy of enhanced gravity separator in processing indian iron ore slime

Abstract

The slime sample was subjected to concentration using Falcon concentrator for their enrichment. The effects of three important variables, eg bowl rotation frequency, back water fl ow rate and per cent solid were studied on the process performance. Increasing the rotation of the Falcon bowl, enable more material to the underfl ow by increasing the yield, whereas, the iron content decreases steadily with increasing the rotation of the bowl. The increase in the back water fl ow effectively removes the clay materials from the underfl ow at the expense of the yield. Similarly, increasing the per cent solid concentration in the feed produces a better product both in terms of yield and Fe content. Results show that EGS/Falcon can be used for processing Indian iron ore slime and producing pellet grade concentrate.
