摘要:Heap leaching is a low-cost technology used in industrial mining to recover precious metals such as gold and uranium, along with several other highly sought after metals like copper, from their primary resources (ores and minerals). For many decades, there has been a growing dema...

摘要:Abstract(#br)Due to decreasing ore grades and increasingly complex ore bodies, the heap leaching of sulfide ores is of increasing interest. In this research, the heap leaching phenomena of a pyrrhotite-rich pentlandite ore was investigated for the first 150 days of operation in o...

摘要:Abstract(#br)A largely electrochemical investigation into the possible use of ammonium chloride or glycine as lixiviants in the heap leaching of chalcopyrite-rich ores has provided good comparative data with which to compare the reagents and also identified several important cons...

摘要:Abstract(#br)In heap leaching, agglomeration of clay rich ores is commonly used and may prevent plugging phenomena within heaps, but is not always successful. In order to better understand the heap leaching process of uranium ore agglomerates, a multi-scale approach, based on 10-...

摘要:Abstract(#br)Gravelly drainage layer and semi-slotted polyethylene pipes are two main components of drainage system of heap leaching structures. Fluid is locally drained and directed to semi-slotted polyethylene pipes by gravelly drainage layer. Then, it is sent to a pregnant ...

摘要:Abstract(#br)Heap leaching is a technology for which there is great interest in developing mathematical models that allow one to simulate, design and optimise the underlying process. Recently, the authors have presented analytical models for heap leaching that describe time ...

摘要:Abstract(#br)Heap leaching technology is finding increasingly widespread application to recover values from low-grade ores, especially in the gold and copper industry. The particular attractiveness of the process is the relatively low-cost recovery of the target metal at site wit...

摘要:Abstract(#br)Heap leaching is an effective and widely used method of recovering metals from low-grade ores. However, the heap leaching technique has not yet been used in other biotechnological processes such as bioremediation. This work describes biostimulation of the native mic...

摘要:Abstract(#br)Heap leaching technology is moving forward rapidly as it satisfies most techno-economic considerations and provides several benefits such as low cost, cleaner environment and product, flexibility, and diversified process conditions. Factors such as proper feed prepar...

摘要:Abstract(#br)A large-scale investigation into the effect of increased aeration on heap leaching of a pyrrhotite-rich pentlandite ore was commenced at the Terrafame mine in Finland. The typical reference air feed amount in operation is approximately 0.05 m 3 /metric ton/h, fed fro...
