Using In Situ Measurements and Modelling to Effectively

stockpile approximately 500 Mt of copper ore, for up to 20 years. Much of the copper is present as the copper sulfide chalcopyrite. Construction of the stockpile commenced in late 2000 and as of early 2007 the pile contained regions more than 100 m high. Oxidation of chalcopyrite in stockpiled ore results in reduced copper recovery during

Mine stockpile design to minimise environmental impact

Calculating Stockpile Capacity

2018-4-8  Calculating Stockpile Capacity: Once the minimum storage capacities which will assure maximum mill output are known, the appropriate stockpile configuration must be determined. Stockpiles fall into two general categories: conical and elongated. Conical Stockpiles The conical stockpile is the simplest and easiest to analyze. The total stockpile
