Heap Leaching of Gold and Silver Ores

 · Processing ore in a mill has higher operating costs and requires more capital investment than processing it in a heap. A heap leach typically achieves ∼25% less gold recovery than a mill. The operating cost plus debt service for a mediumsized mill (3000 t/d) is typically 39/t of ore treated, whereas the comparable cost for the heap is 19/t, equating to a differential operating cost plus ...

Mineral Processing Wastes

Typically, mill tailings range from sand to siltclay in particle size (40 to 90 percent passing a mm (No. 200) sieve), depending on the degree of processing needed to recover the ore. The basic mineral processing techniques involved in the milling or concentrating of ore are crushing, then separation of the ore from the impurities.

Tailings

The extraction of minerals from ore can be done two ways ... ranging from the size of a grain of sand to a few micrometres.
