| Description |
In this investigation an estimate of SPM generated on simulated industrial crushing without proper dust collection system is carried out at laboratory. The SPM level was found to be 1496.09 ug/m3 without dust collection system which is much higher then the specified limit. Thus calls for proper during processing of iron ores was treated in a wet high intensity magnetic separator (WHIMS) and flotation. It was possible to produce concentrate with Fe content of 64.9% having yield of 48.7% by WHIMS and 64.5% having yield of 47% by flotation. That can be directly used as pellet feed to DRI plants. The remaining waste material may be treated with flocculants such as starch-alum combination followed by solid/Liquid separation for safe disposal.
