The Blue Mountains gold belt in eastern Oregon, USA, produced some 48 t (∼1.7 M oz) of orogenic gold from narrow veins, not including placers, mostly during the late 1800's and early 1900's. The belt is loosely defined as the region bounded by the 45°N, ∼44.25°S, ∼117°W, and ∼ 119°W ( Fig. 1, Fig. 2 ).
The process is characterized for its economic cost against the agitated leaching process when the ore deposit has a low gold content. Typically the process can process ores whose gold content is 0.8-1.1 g/t. The leaching solution is spread at the top of the pile and the pregnant solution will have to percolate through the pile.
Getting useful crafting materials out of the world-generated Ore Blocks in GregTech 6 has become less forumlaic than it was in GregTech 5, but more optional side paths have been added.
