Abstract
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.
