Achieving Reliable Gravity Discharge from Ore

The Need. As a result of segregation, even the presence of as little as 10% fines (-5 mesh) in an ore can lead to serious flow problems in stockpile reclaim via tunnel systems. If the fines are cohesive and gain strength as a function of consolidation pressure, then ratholes may form above discharge hoppers, severely reducing the live capacity of ...

Ore Stockpiling – Why are we doing this again?

The software will track grades in the stockpile and sometimes be able to model stockpile balances assuming reclaim by average grade, or first in-first out (FIFO), or last in-first out (LIFO). Stockpiling in most cases provides potential benefits to an operation and the project economics.

Upgrading low grade gold ore stockpiles - Mineral

01-03-2017  Upgrading low grade gold ore stockpiles. Sensor-based automatic ore sorting technologies are used in the minerals industries to efficiently remove waste and sub-marginal grade material from crushed and screened run of mine (ROM) ore, producing a coarse (typically >10 mm) upgraded pre-concentrate at an early stage in the mineral processing circuit.

The importance of coarse-ore stockpile design.

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.

Role of pre-crusher stockpiling for grade control

Whereas this design suits the mining process and is operationally simple, there can be little confidence in the grade of the ore that is fed to the crusher. This makes short-term grade control difficult and reconciliation back to the mine face imprecise. Well-designed and operated pre-crusher stockpiles can overcome these deficiencies.

Crusher - an overview ScienceDirect Topics

Crushed ore feeds this bin continuously and the bin overflows to a small conveyor feeding a dead stockpile. In the event of a primary crusher failure, the crusher loader is used to reclaim the stockpile via the surge bin, which doubles as an emergency hopper. • For coarse ore, the next alternative is a coarse ore stockpile.
