stockpiles types in mining

Financial Modelling of Stockpiles in a Mining Project ...

Mining schedule in inputs sheet – foundation for stockpile calculations. The mining schedule is a summary of the physical aspects of the mining process and is usually provided by the engineers. At its most basic level it should contain (screenshot 1) ore mined (tonne) and the corresponding ore grade (grams/tonne) for each type of ore.

MiningMath's Knowledge Base - Stockpiles

Stockpiles are a post-processing unit of the algorithm. Therefore, after the optimization, which generates mining surfaces, the algorithm does its analysis among the discarded blocks. MiningMath checks if the block's values (Revenue - Fixed Mining Cost - Rehandling Cost) is higher than the cost of discarding it, with the respective discount rates applied at the period of extraction and period ...

Ore Stockpiling – Why are we doing this again?

28/04/2016  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 stockpiles at site. 2. Grade Optimization: This stockpiling approach is used in situations where the mine delivers more ore than is required by the plant, thereby allowing the best grades to be processed directly while lower

Side reclaimers work for both types of stockpiles, longitudinal or circular. The bulk material can be reclaimed from the front or the side. When reclaiming from the side, scraper chains move the material on a belt conveyor. Front reclaiming usually uses a rake that in small side-to-side movements pushes the material on a scraper chain to be transported further to the conveyor. The advantage is ...

While mixing is one of the types of mixed coal can still be located in a small quantity of material mixed results from two or more types of coal. Storage process, can be done: - Near the mine, usually still be lumpy coal - Near the harbor - And in place of coal users for the expected storage period is not too long, as it will result in a decline in the quality of coal.

Soil Stockpiling for Reclamation and Restoration ...

Stockpiles are often meters deep. When mining operations are complete, the overburden material is reapplied and leveled and then the topsoil is reapplied and spread over the overburden material to provide a planting medium (USDA Forest Service RM-447). Both removal and replacement of the soil layers involves the use of heavy equipment. Because mining operations involve removal and storage

The Role of Precrusher Stockpiling for Grade Control in

The different types of grade variability in mining are reviewed in this paper. The role of precrusher stockpiles in reducing short-term variability is discussed and their ineffectiveness in addressing long-term variability is highlighted. Their role in removing the serial correlation of the extracted ore is explained. Precrusher stockpiles carry out the four, at times competing, objectives of ...
