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. The most obvious is the fracture of larger lumps. It could be argued that this is beneficial when the process involves oreGRADE CONTROL BLENDING AND SELECTIVITY FOR OPTIMAL,STOCKPILE MANAGEMENT AND BLENDING Stockpile tipping and reclaiming faces are strictly monitored and surveyed (Figure 3). Ore is reclaimed perpendicular to the tipping direction. The average grade of a particular stockpile is the average grade of ore mined during a certain stockpileOre Stockpiling – Why are we doing this again?,28.04.2016· 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 grades are stockpiled for a future date. Possibly one or more grade stockpiles may be used, for example a low grade and a medium-low grade stockpile. Such stockpiles may not get processed for years, possibly until the mine

Ore Blending as Mine Scheduling Strategy to

01.01.2013· MINE SCHEDULING Ore blending from different stockpiles that represents different nickel grades usually done in the operation. Mine scheduling is commonly used to determine the sequence of mining excavation from a nickel deposit, also to consider what happens to the loose material after it has been mined. In this matter, the material from pit goes to different stockpiles based on grade criteria.
