Surface stacking is the disposal of tailings on the surface of the ground. As a nonsettling, nonsegregating suspension of solids, minimal water is released into the impoundment and the stacked tailings dries significantly faster than conventional ponds where fines (slimes) segregate and can seal the surface of the deposit, preventing drying.
iron ore production to 155 million tons per annum, the slime generation is expected to be above 1012 million tons. Further, with the rapid increase in the projected iron and steel making capacity in India, utilization of these slimes as sources of iron values is imperative. At present these slimes .
The studies on hydrocyclone and magnetic separation had indicated that an iron concentrate of 61 – 65 per cent Fe could be obtained by recovering 59 – 78 per cent of the iron values present in the slimes. Depending on the nature of the slimes the alumina and silica levels have been brought down to and per cent respectively.
