The best method for sampling is invariably during movement of cargo – either during construction of a stockpile when ore is being delivered to the stack or during movement of ore from a stockpile for loading onboard a barge. However, often this is impractical for a number of reasons, such as the requirement for provision of information
1.2.2 Ore Stockpile and conveyor The stockpile areas are proposed to provide the necessary flexibility to ensure continuity of supply of iron ore to steel mill customers. The construction of a dredge spoil bund is planned, using sandy material from within the proposed stockpile (~40 ha) and sourced externally if required (Figure 1.3).

Experimental Study of Stockpiles of Iron Ore Fines. 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 .
ORE TRACKING: Mining equipment implemented for ore extraction is optimal for selective mining. Material from the pit is transported to various stockpile destinations. These include high-grade (>13% Zn), medium-grade (9 - 13% Zn), low-grade (4 - 9% Zn) and marginal (1 - 4% Zn) ore stockpiles. Limestone (Ca >28%) from the pit is mined for plant acid
