原始语种摘要: Abstract(#br)A method is provided for deriving the average macro-scale batch leaching kinetics of ore on a commercial heap on which portions of the heap (or cells) possess a range of leaching ages due to irrigation commencing while stacking is still in progress. It has been designed to require as only inputs the average ore grade, daily amount of ore stacked and the rate of metal extraction to a common drainage collection point for all cells.(#br)A comparison of the batch curve, thus derived, with the batch curve upon which the design of the pad footprint was based provides an early indication of the likelihood of reaching the desired rate of metal production. Furthermore, any attempt to fit the performance of a leaching model to that of a commercial heap requires the description of heap...
