Contending with stockpile segregation, product quality - Quarry

As the stockpile is being built, the conveyor moves left and right radially. The end toe of the pile, which is normally coarse material, will be covered with fine material as the conveyor travels radially. The front end and back toe will still be coarse material, but the stockpile will be blended more than a conical pile.

How to Collect Aggregate Sample From Stockpile?

Using a front end-loader, dig into the stockpile and set aside small pile of 10 to 15 ton of material. When forming the small pile, the loader bucket must be kept as low as possible and roll the material from the bucket rather than dumping the material. This technique is applied in order to reduce segregation of aggregate.

Bulk ore sorting improves profitability and sustainability

By removing coarse barren material, pre-concentration has the potential to significantly reduce the amount of material that requires downstream processing. If conducted close to the mining face, it can potentially reduce ore transport requirements by rejecting barren gangue and transporting less ore to the processing plant.
