We currently have our flagship mining operations at Assen Iron Ore Mine, 65km north of Brits on the R511 road. We are contracted to mine 120 000 tons of iron ore run-of-mine (ROM) per month for three years. Our current contract commenced in August 2016.
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 …
Calculating Stockpile Capacity: Once the minimum storage capacities which will assure maximum mill output are known, the appropriate stockpile configuration must be determined. Stockpiles fall into two general categories: conical and elongated. Conical Stockpiles The conical stockpile is the simplest and easiest to analyze. The total …

The iron ore mine currently has an abundance of OFF grade ore stockpiles due to the prioritising of ON grade ore at the plant. Stockpiling is included in the five-year and 12-month rolling plans. If the ore that is mined is more than what the plant can process, it is then sent to the stockpiles.
Purpose In the mining industry, a run-of-mine (ROM) stockpile is a temporary storage unit, but it is also widely accepted as an effective method to reduce the short-term variations of ore grade.

We design and manufacture in multiple locations around Australia. We are strategically located close to major mining areas so we can service our …
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-

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.
of-Mine (ROM) stockpiles, and multiple stockpiles together form a stockyard. To fulfill the next step in the mining value chain up-stream, the stockpile scheduler should select a blend of stacked material in ROM stockyard to prepare for delivering with respect to the end-user requirements such as chemical concentration and
