For instance, a logic was implemented that allows trucks to be rerouted to a stockpile with a grade and hardness range fitting the loaded ore, if the tip pocket is utilized fully. In addition, two methods for the grade blending were implemented. Blending on the coarse ore stockpile happens according to .
Apr 28, 2016· 3. Surge Control: Surge piles 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 .
Coal homogenization refers to the process of mixing coal to reduce the variance of the product supplied. This homogenization process is performed during the coal stockpiling operation. Although the terms blending and homogenization are often used interchangeably, there are differences as the definitions show. The most notable difference is that blending refers to stacking coal from different ...

at Swartberg was commissioned. The Swartberg mine is located 7 km from Broken Hill and ore is hauled by truck to the surface ore pad at Broken Hill. In this way, Black Mountain can maintain an annual production rate of Mt/a (Figure 2). However, the blend of Swartberg ore with Broken Hill ore poses specific processing problems. The
Crushing: Crush ore grade material from the mine to between five and seven inches in size. Grinding: Feed coarse ore stockpile onto conveyor belts and deliver to a grinding mill where it is mixed with water; five inch steel balls grind the ore to create a coarse slurry.
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.

The chalcopyrite has a higher liberation level in comparison to the pyrite ore types, and the copper recovery is higher, and a higher concentrate grade is more easily achieved. Blending is critical for the operation with ROM stockpile grades varying from 1 per cent Cu to >15 per cent Cu.
For many mining projects, the open pit/cut mining process often begins months or even years before the milling plant starts operating. The buildup of stockpile requires careful treatment to ensure the right grade of the ore milled is modelled and that the right value of this stockpile is .
