Waste rock pile characterization, heterogeneity, and
Mine waste rock piles (MWRPs) are anthropogenically created landforms in present and past mining areas that are derived from open pit and underground mining methods Surficial oxidation of sulfide minerals of MWRPs is a major cause of acid drainage and can increase concentrations of toxic metals downgradient from them This waste rock pile is located at the northwest portion of the mining complex and covers an area of 644 ha, with a volume of 148 million m 3 of waste material [ 30 ] This local comprehends an old valley which was covered by mining wastes and, eventually, is exposed to atmospheric precipitationHydrogelogical characterization of a waste rock pile and waste generated by many mining operations is waste rock, or overburden Waste rock, which consists of rock and target minerals in concentrations too low for economic recovery, is removed along with the ore Waste rock includes granular, broken rock that ranges from fine sand to largeOffice of Wastewater Management Hardrock Mining Wastes

Mining operations can generate enormous amounts of waste (ie waste rock and tailings) that must be managed and handled in a way that avoids negative environmental impact In Sweden, the mining industry accounts for over 80 percent of the total waste production each year (2015) Numerical modelling of transfer processes in a waste rock pile undergoing the temporal evolution of its heterogeneous material properties International Journal of Mining, Reclamation and Environment: Vol 29, No 6, pp 499520Numerical modelling of transfer processes in a waste WASTE ROCK Waste rock is produced during open pit mining when overburden is removed, and during underground mining when driving tunnels through nonore zones Piles of socalled waste rock often contain elevated concentrations of radioisotopes compared to normal rock Other waste piles consist of ore with too low a grade for processingUranium Mining and Milling Wastes: An Introduction

Remediation at former mining sites containing waste rock piles (WRPs) commonly involves the installation of a cover system over the waste rock to limit water and oxygen ingress and attenuate the impacts of acid mine drainage (AMD) to the environment (2015) Numerical modelling of transfer processes in a waste rock pile undergoing the temporal evolution of its heterogeneous material properties International Journal of Mining, Reclamation and Environment: Vol 29, No 6, pp 499520Numerical modelling of transfer processes in a waste WASTE ROCK Waste rock is produced during open pit mining when overburden is removed, and during underground mining when driving tunnels through nonore zones Piles of socalled waste rock often contain elevated concentrations of radioisotopes compared to normal rock Other waste piles consist of ore with too low a grade for processingUranium Mining and Milling Wastes: An Introduction
The difference between waste rock and tailings
During mining, we will place all waste rock and tailings on engineered liners similar to those used by community landfills or industrial solid waste disposal facilities During closure, the waste rock will be used to backfill the mine pit The tailings and any remaining waste rock will be covered and monitored per Michigan’s mining regulations waste rock properties within piles can therefore present a high degree of heterogeneity (Fala et al, 2012) Fine and coarsegrained layers alternate in the pile profile as the waste rock pile grows (Anterrieu et al, 2010; Azam et al, 2007) Waste rock at the surface of each bench can also be crushed and compacted by heavy equipment during theWaste rock disposal and segregation: Validation and
