2014-1-17 versus the Iron Ore Fines Stockpile Scale Model . Samples with 50 kg of pellet feed (iron ore fines) were used to form the scale models of the stockpiles set out in the iron ore mine production yards. The density value for the sample is 5.35 g/cm. 3. This sample was called sample 1 in this article. We applied the formulation [1] for the ...

A framework for modelling a stockpile believed to be readily workable for most modern mines through use of established geostatistical modelling techniques applied to the type of data generated in a FMS is demonstrated. The frequent best practice for managing large low-grade run-of-mine (ROM) stockpiles is to average the entire stockpile to only one grade. Modern ore control and mineral ...

2016-4-28 1. Campaigning: For metallurgical reasons if there are some ore types that can cause process difficulties if mixed with other ores. The problematic ore might be stockpiled until sufficient inventory allows one to process that ore (i.e. campaign) through the mill. Such stockpiles will only grow as large as the operator allows them to grow.
