This may be done if the uranium contents is too low for the ore to be economically processed in a uranium mill The leaching liquid (often sulfuric acid) is introduced on the top of the pile and percolates down until it reaches a liner below the pile where it is caught and pumped to a processing plant During leaching piles present a hazard because of release of dust radon gas and leaching

How you leach your acorns depends on how you want to use your nuts Hot leaching (boiling) cooks the starch in the nuts meaning they won't bind well as a flour However hot leaching is fast and if you plan to use your acorns as snacking nuts or as a soup base this is a good way to go

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 medium-sized 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
