Ore Stockpiling – Why are we doing this again?

Apr 28, 2016 · Such stockpiles will only grow as large as the operator allows them to grow. At any time the operator can process the material and deplete the stockpile. Be aware that mining operations might still be mining other ore types, then those ores may need to be stockpiled during the campaigning. That means even more ore stockpiles at site. 2.

Environmental impact of iron ore mining Wikipedia

Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)·n(H 2 O)) or siderite (FeCO 3).

About ore blending & stockpiles: Since the function of the stockpile is to act as an ore reservoir rather than as an ore processor, the action of forming a stockpile should have as little effect as possible on the material. Several undesirable effects are produced by discharging the material from too great a height above the stockpile.
