Percolating liquids
Stacking rather than truck
dumping, the importance
of modelling, subsurface
leaching: John Chadwick
considers these and much
more, including some
innovative new ideas in
leaching
eap leaching may appear to be simple
but it is in fact a very complex process.
“A plethora of technologies such as
material handling, environmental control,
analytical techniques, solution chemistry,
hydrology and many others contribute to the
design and operation of a heap leach. Heap
leaching requires an inter-disciplinary approach
between geologists, mining engineers and
metallurgists2.
“Many oper
