Apr 28, 2016· 1) Will the stockpile oxidize over time? If so how will this affect recovery? 2) What recovery factor should be used for fresh stockpile? Should it be the same as for run of mill ore? Most planners use the same number. 3) Is the stockpile grade tested or is is just a mathematical calculation at month end reconciliation?

Coarse ore to primary screening from the coarse ore stockpile is nominal 8″ and the fine crushed product is sized to 80% minus ½". Table 4 lists the operating criteria of the fine crushing plant. A separate building located in front of the coarse ore stockpile houses the primary screening equipment.
The crusher feeds, via an apron feeder, a coarse ore stockpile that has a 91,800 t live capacity. In turn, five apron feeders reclaim ore from the coarse ore stockpile to two semi-autogenous grind (SAG) mills operating in closed circuit with pebble crusher. Each SAG mill operates with two ball mills.
In 2009, the Company initiated this phase of the modernization project which included an inpit crusher and conveyor system, increasing regrind and cleaner flotation capacity, the installation of a two-stage tailings pumping system plus a new coarse ore stockpile and SAG direct feed system.
Sep 26, 2017· Blending on the coarse ore stockpile happens according to a user-specified recipe. In other words, the user specifies a percentage for each pile that is converted into a rate at which the pile is drawn down. This allows balancing out periods of low or high grade by blending in stocked ore.
5. Coarse Ore Stockpile – The coarse ore stockpile shall be surrounded by a pole structure with an enclosure on the top and two sides (ARM 17.8.752). 6. Apron Feeders – A wet scrubber shall control particulate emissions from the coarse ore stockpile transfer to the apron feeders (ARM 17.8.752). 7.
A third ball mill takes a split of feed from each module to assist maintaining a target product size. Both modules are fed from the same primary crushing circuit via a Coarse Ore Stockpile (COS) which provides surge capacity. The grinding circuit is designed to produce a product size suitable for the downstream froth flotation process.

The primary crusher may send the crushed ore on to a secondary crusher or pile it directly onto the coarse ore stockpile. TOUR NOTE: On your tour from the Mineral Discovery Center, you may get to see the haul trucks dumping ore into the crusher. Grinding The ore is ground into a fine powder by large rotating mills. The two types used in the ...

Blending on the coarse ore stockpile happens according to a user-specified recipe. In other words, the user specifies a percentage for each pile that is converted into a rate at which the pile is drawn down. This allows balancing out periods of low or high grade by blending in stocked ore.
Ore is delivered from the pit to a primary crusher, crushed and then discharged by conveyor belt to a coarse ore stockpile. Ore is drawn from the coarse ore stockpile by conveyor belts feeding a vibrating screen with oversize in turn passing through a secondary standard cone crusher.
The trajectory of the ore as it leaves the conveyor belt will determine where in the bin or pile each size of the crushed ore will land. Once in the bin, another stage of classification takes place. The smaller ore due to its lesser size and weight, tends to filter downwards faster than the coarse material does.
May 24, 2011· Stock Pile Segregation ... If the gradation is too coarse (you pulled the aggregate only from the outside of the stockpile) your pavement can have poor compaction, raveling, and/or rutting.
