mining, modelling, cut-off grade, stockpiling, optimization. Introduction Cut-off grade is the criterion that discriminates between ore and waste within a given mineral deposit1,2. If material grade in the mineral deposit is above cut-off grade it is classified as ore, and if material grade is below cut-off grade, it is classified as waste.
53. Ore Stockpiling – Why do it? | KJ Kuchling Consulting Ltd.
Surge Control: stockpiling may be used in cases where the mine may have a fluctuating ore delivery rate and on some days excess ore is produced while other days there is underproduction. The stockpile is simply used to make up the difference and provide a steady primary crusher feed rate.
The Iron Ore Stockpile and Dispute Activity in the ...
It is a conventional wisdom among workers in the Pilbara iron ore mining industry that management engineers disputes when the stockpiles are high and settles disputes when stockpiles are low. This paper investigates the evidence for a relationship between iron ore production and dispute activity.
The importance of coarse-ore stockpile design. - Jenike
The major impact of the lower-than-desired live storage capacities on the economic result of the mine plus processing plant complex is orders of magnitude higher than the costs of an ore characterization and flow property testing program, followed by an adequate stockpile design.

Ore mined from two pits (Ajopa pit and Block 8) are sampled using a reverse circulation drilling method. Ajopa rompad stockpile contains ore from Ajopa pit denoted as Fingers 1, 2 and low grade. Some of this ore is re-handled into a stockpile at a rompad close to …
Fine Ore Storage Bin and Stock Pile
It begins on the conveyor belt as it is taken to the fine ore bin. The shaking and vibration of the belt makes the finer particles of ore settle in to the spaces between the larger ore until the majority of the smaller rock is on the bottom of the load, near the surface of the conveyor belt.
A Simplified Economic Filter for Open-Pit Mining and Heap ...
transportation costs. Mining costs are modeled in terms of U.S. dollars per ton of ore and waste mined and milling costs in terms of U.S. dollars per ton of ore processed; hence the two costs models cannot be added together to yield mining and milling operating costs on a common basis such as per tons of ore mined and milled without conversion. To
Computer aids for production systems management in iron ...
Operational differences occur between mines, departing from the sequence outlined above. The ore from some mines is crushed into fines, instead of being separated into lump and fines products. In some operations, the ore is crushed, assayed and stockpiled at the mine, before railing.
Some observations on copper yields and ore grades ...
The existence of by- and co-products, and changing relative prices of those and copper need to be recognized when looking at trends in copper yields over time, at differences between individual mines and national or regional averages and at the relationship between copper ore grades and copper prices.

Gloria Mine is extracting manganese at depths that vary between 180 to 250 metres. Ore is crushed underground before being conveyed to surface stockpile via a decline shaft. Ore is withdrawn from the surface stockpile and forwarded to two stages of crushing, dry screening, and wet screening to yield lumpy and fine products.

The ore will be crushed to a P80 of 170 mm and stored in a conical stockpile ahead of the grinding circuit. The crusher will discharge on a belt conveyor, which will transport the ore to the conical stockpile containing approximately 30,000 tonnes of live storage. A storage dome for dust control will cover the stockpile.

The ore is hauled directly to a gyratory crusher and coarse ore stockpile area south of the pit. The crushed ore is fed to two semi-autogenous (SAG) grinding mills, followed by two ball mills and one regrind mill. Flotation circuits are then used to produce a gold-copper-silver concentrate.
Common & Basic Formulas for Mineral Processing Calculations
The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams.

volume. The relationship between whole-rock chemistry and density is non-linear, which is especially obvious when there is a marked difference in SG between the different mineral phases (Lipton and Horton, 2014). Determining bulk density from larger samples Bulk samples may be obtained if trial mining or production is already in progress at a site.
