Hello Group,
Does anyone have suggestions re determining the -6.2mm fraction of a stream of iron ore?
This ore is sourced at an inland facility where it's already screened to provide +6.2, and then railed to the port and stacked onto chevron ply stockpiles at the port.
The reclaimed ore is sent to the ship via a screenhouse, and the return fines fraction is sent back to "fines" stockpiles. We are seeing unexpected variations in the amount of fines returned. Not only is there "too much", but also this amount slews from "normal" to "excessive" and back again over a minute or two. Two things immediately spring to mind:
a) We need to see if we are getting spec material coming in on the trains, and b) We need to see if the ore is being subjected to too much attrition in out process
To this end, we would like to be able to see what the -6.2mm fraction is, of the ore as it is in transit. First Prize would be a (semi)portable unit that could analyse the iron ore pre- and post- stockpile.
