  • Ore Blending - Geology Geometallurgy - Metallurgist ...

    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.

  • Ore Stockpiling – Why are we doing this again?

    Apr 28, 2016  Such stockpiles will only grow as large as the operator allows them to grow. At any time the operator can process the material and deplete the stockpile. Be aware that mining operations might still be mining other ore types, then those ores may need to be stockpiled during the campaigning. That means even more ore

  • Stockpile Management Challenges in Mining

    Having a stockpile provides distinct advantages for mining companies – For ex: It acts as a buffer against supply fluctuations and it enables grade maximization by blending. However, managing stockpiles has a cost to it and having excess levels of stockpiles will only negate the benefits.
