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.

Automatic quality estimation in blending using a 3D stockpile

The results show that the stockpile model is not sensitive to variables such as the ore size distribution, ore size range and RFID tag size, while wall friction, stockpile feed belt speed, segregation in the ore flow region and contact model have a significant effect on ore blending within the stockpile.

3D Stockpile Modelling to Improve the Quality Control …

When a batch of iron ore is transported to a stockpile, the ore is stacked selectively according to the quality composition so that it would optimize the homogeneity in quality of that stockpile. A complete stockpile may contain more than hundred thin layers. The mix of these layers occurs when the stockpile is recovered by a reclaimer slice-by-
