Uranium Mining Overview - World Nuclear AssociationOpen pit and underground mining
Where orebodies lie close to the surface, they are usually accessed by open cut mining, involving a large pit and the removal of much overburden (overlying rock) as well as a lot of waste rock. Where orebodies are deeper, underground mining is usually employed, involving construction of access shafts and tunne…In situ leach (ISL) mining
Some orebodies lie in groundwater in porous unconsolidated material (such as gravel or sand) and may be accessed simply by dissolving the uranium and pumping it out – this is in situ leach (ISL) mining (also known in North America as in situ recovery - ISR). It can be applied where the orebody's aquifer is confi…Heap leaching
Some ore, usually very low-grade (below 0.1%U), is treated by heap leaching. Here the broken ore is stacked about 5 to 30 metres high on an impermeable pad and irrigated with acid (or sometimes alkaline) solution over many weeks. The pregnant liquor from this is collected and treated to recover the uranium…See more on world-nuclear.orgsp.info ProManure E2200 - Electric motor-driven pumpProManure E2200 - Electric motor-driven pump.
