6 Potential Environmental Effects of Uranium Mining, Processing, and Reclamation. ... Management of waste rock piles at uranium mines has evolved from the realization that all waste rock does not behave the same geochemically. The presence of metal sulfide minerals in portions of the waste rock is a cause of particular concern because of the ...
Nov 18, 2017· Western Australia: Mulga Rock Uranium Project threatens environmental impacts from Tailings waste: Briefer (Nov 2017) by David Noonan, Independent Environment Campaigner. Uranium mining has unique, inherent risks and long term impacts. The West Australian Parliament has passed a Motion (Legislative Council 23 May 2012) recommending:

Waste characterisation is the study of the environmental impacts of mining waste during mining, processing and above ground storage of ore prior to treatment. Waste characterisation needs to consider whether the waste will cause: acid & metalliferous drainage (AMD) saline and/or sodic drainage (i.e. neutral mine drainage) leaching and mobilisation of metals and toxic compound
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): In many cases the placement of engineered cover systems on uranium mining waste dumps and tailings is required to avoid, or at least to reduce, pollution of water resources. In this paper, the failure mechanisms of cover systems containing a clay liner are set out and discussed, and essential design and construction ...
of concern include waste rock/overburden disposal, tailings, heap leaches/dump leaches, and mine water. Waste rock/overburden is the soil and rock mining operations move during the process of accessing an ore or mineral body. It also includes rock removed while sinking shafts, and accessing or exploiting the ore body and rock bedded with the ore.

The Agency proposed to list waste rock and overburden from uranium mining and overburden and slimes from phosphate surface mining because of concern about their radioactivity. The proposal also considered any other mining wastes that were ignitable, corrosive, reactive, or EP toxic as hazardous waste.
Very little waste rock results during actual mining, as nearly all the mined material is sent to either a screening plant (that is, tipple) or a washing plant, where waste is rejected as refuse. Waste rock which does result is typically disposed of in a surface dump site, located near the mine portal. In some instances, waste rock is disposed ...
