Effect of scale of operation on heap leaching

Effect of scale of operation on heap leaching performance. The extent to which differences in bulk density and in irrigation geometry contribute towards the differences observed in leaching performance between laboratory-scale columns versus commercial-scale heaps was investigated. Furthermore, the contributions of segregation and stratification,

Multi-scale quantification of leaching performance

2016-9-1  The performance of heap leaching is dictated by a large number of processes acting at a wide range of length scales. One important scale is that of the individual particles, where the interaction between the rate kinetics at the surfaces of the individual mineral grains and the mass transport through the particle combine to give the overall apparent particle scale kinetics.

Optimization of the Heap Leaching Process through

The performance of heap leaching depends on many input variables (operational and design), which means its optimization is complex . The materials are leached with various chemical solutions that extract valuable minerals.

oxide and sulfide ores [3]. Heap leaching has been demonstrated as a viable and low cost approach to open-pit mining operations with low-grade and complex run of mine (ROM) ores, agglomerated flotation tailings and also for the treatment of coarse rejects from semi-autogenous grinding (SAG) circuits [4]. Modern heap leaching might be defined

2019-4-16  In general, heap leaching keeps capital investment low, construction of a heap leach operation is rapid, and production costs are low. Heap leaching can make mining low grade metal ores profitable, particularly as part of and open pit mine with low stripping ratios. The primary disadvantage of heap leaching is low recovery efficiencies.
