At a prospect scale, mineralisation is interpreted to occur as steeply southwest dipping stratiform mineralisation, remobilised in part into a bedding parallel structurally controlled lode. The mineralised zone has an average true width of approximately 15m. From current artisanal workings, mineralisation occurs over a strike length of about 450m in a southeast direction and is open to the ...

IH 2010-001 Reply Impacts of Gold Extraction in the EU

First used on a large scale in the 1970s, cyanide heap leaching allows miners to extract microscopic gold flecks from low-grade ore. In a typical heap leach operation, vast quantities of rock are crushed and piled onto clay and plastic liners in huge decks. A sodium cyanide solution is sprayed onto the mound, passes through the rock layers, and in doing so extracts the gold out of the ore. Up ...

Valuable chalcopyrite copper, previously not considered economical in heap leach development, is now heap leached, as is nickel laterite, uranium, and even rare earths. The growth of heap leaching is heavily tied to the massive scale on which mines are being built, with some sites requiring huge investments. Heap leach stacks can near 200m as operations look to more quickly prove and sustain ...

In the case of gold recovery, heap leaching generally requires 60 to 90 days to leach the ore, compared to the 24 hours required by a conventional agitated leach process. Gold recovery is also usually only 70% compared with 90% recovery in an agitated leach plant. Other metals, such as copper, use solvent extraction and electrowinning to extract the target metal from the solution.

The run-of-mine alternative models a direct mine-feed of assumed maximum size of 610 mm (24"). This is directly fed to the heap leach pads without crushing by mine haul trucks. Material is then distributed on the pad by bull dozers. The mine plan and gold recovery process from pregnant solutions is the same as the Base Case alternative.
