Iron ore stockpile
The iron ore stockpile (formerly known as the "ore cutter") is a construct used to store iron blocks. It's required in order to later process these blocks at the stone cutter or stone cutter II into iron ore. It does not have any particular function of its own outside of this. Only 7 blocks of iron can be stored in a stockpile at a time. The one that can be built in the …

The paper aims to obtain more homogenous iron ore grade by redesigning current rehandling strategy and creating selective Run of Mine (ROM) with defined Fe grade and contaminants tolerances in the ...
Fine Ore Storage Bin and Stock Pile
Let's begin with fine ore storage bin or stockpile, get it out of the way and then proceed to grinding. You would think that there isn't that much to learn about when talking of fine ore storage, after all, all that this area is really for is to provide surge capacity for each of the circuits. True, but there are a couple of things that ...

3D stockpile modelling and quality calculation for continuous stockpile
Iron ore is one of Australia's major export products. Its quality is normally governed by two factors during exports: the chemical composition of the iron-ore body and the short-term chemical variations. The latter is the main criterion because blast furnaces are relatively inflexible and require a tightly defined quality specification.
